Changelog xz-utils (5.2.2-1.3ubuntu0.1)


xz-utils (5.2.2-1.3ubuntu0.1) bionic-security; urgency=medium

   * SECURITY UPDATE: arbitrary file overwrite or code execution with
     crafted file names
     - debian/patches/CVE-2022-1271.patch: fix escaping of malicious
       filenames in src/scripts/
     - CVE-2022-1271


xz-utils (5.2.2-1.3) unstable; urgency=medium

   * Non-maintainer upload.
   * Force a constant /bin/sh for installed scripts. This helps the build
     be reproducible; /bin/sh on Debian is always POSIX. (Closes: #806331)


xz-utils (5.2.2-1.2) unstable; urgency=medium

   * Non-maintainer upload.
   * link against libfreebsd-glue on kfreebsd-* (Closes: #840063)

xz-utils (5.2.2-1.1) unstable; urgency=medium

   * Non-maintainer upload.
   * switch to git-dpm for packaging (closes: #540405)
   * New Upstream (closes: #731634)
    - no more "xzless error in line 49" (closes: #693537)
    - xzgrep -h works (closes: #780268)
   * update symbol file
   * enable threads for the "normal build"


xz-utils (5.1.1alpha+20120614-2.1) unstable; urgency=medium

   [ Helmut Grohne ]
   * Non-maintainer upload.
   [ Colin Watson ]
   * Remove build-dependency on perl; we use no non-trivial Perl modules so
     the Essential perl-base is perfectly adequate, and an unadorned
     build-dependency on perl is problematic for cross-building.
     Closes: #697328.


xz-utils (5.1.1alpha+20120614-2) unstable; urgency=low

   * Apply fixes from 5.1.2alpha.  Closes: #685220.
     - liblzma: report a LZMA_DATA_ERROR when range encoded data starts
       with a nonzero byte.  This is a sanity check to catch malformed
       files that no known encoders produce.
     - xz -v -v --list: Support for decompressing blocks with
       zero-length uncompressed data was added in xz 5.0.2, not 5.0.3.
     - xz.1: "xz --robot -v -v --list" gained a "minimum xz version to
       decompress" field.
   * xz-utils/README.Debian: Document differences from upstream.
     Closes: #685217.

xz-utils (5.1.1alpha+20120614-1) unstable; urgency=low

   * New snapshot, taken from upstream commit f1675f76.
     - liblzma: BCJ filters would return a spurious LZMA_BUF_ERROR
       result in certain circumstances.  As a result, the xz tool
       could produce inappropriate "Compressed data is corrupt" or
       "Unexpected end of input" failures (reported in XZ Embedded as
       Fedora bug 735408).
     - "xz -v -v --list" prints the minimal XZ Utils version needed
       to decompress a stream.
     - "xz --robot -v --list" formats filenames more plainly.
     - xzgrep does not fail unconditionally when the decompressor
       dies with SIGPIPE due to unconsumed output any more.  This
       makes the exit status from commands such as "xzgrep -q" and
       "xzgrep -l" more predictable and convenient for scripts.
     - examples/xz_pipe_decomp.c did not check correctly for
       truncated input.
     - There is a new set of sample programs.  The old ones have
       been renamed to examples_old but are still maintained.
   * liblzma:
     - If dlopen() indicates that is loaded, check fewer
       reserved fields in the stream argument to the lzma_code()
       function.  This prevents out-of-bounds reads when liblzma5
       functions are called by code built against liblzma2 (see
     - Remove the lzma_code@Base compatibility symbol.
       Closes: #649522.  Thanks to Eduard Bloch.
     - Install run-time library to /lib so it can be used before /usr
       is mounted.  Closes: #672120.
     - Configure with --disable-threads for now to avoid needlessly
       linking to libpthread and librt.
   * liblzma-dev:
     - Install an appropriate library for static linking instead of
       the decompression-only version used to build xzdec.
       Closes: #673001.  Thanks to Anton Tolchanov.
     - Use the liblzma2-compatible version of lzma_code() in the
       static library.
     - Multi-Arch: same.  Thanks to Riku Voipio.
     - Install new examples and revised old examples to
   * xz-utils:
     - Use update-alternatives to provide lzma, unlzma, lzcat, and
       the rest of the lz* scripts without conflicting with the lzma
     - Conflicts: lzma versions before before 9.22-1, when it started
       providing lzma, unlzma, and lzcat through the alternatives
     - Conflicts: and Replaces: xz-lzma.
     - README.Debian: Update instructions on configuring the package
       to provide lzma compatibility commands.
   * Remove xz-lzma package.
   * Use dpkg-buildflags to retrieve compiler flags, including
     hardening options.  Build-Depends: dpkg-dev (>= 1.16.1).
     Closes: #653739.
   * debian/rules:
     - build-arch: Simplify by using a double-colon rule instead of a
       dependency on a dummy noop target.
     - build-indep: Assume doxygen is available, instead of trying to
       get by by assuming the caller meant to invoke build-arch when
       it is missing.  Build-Depends: dpkg-dev (>= 1.16.2).
     - Rearrange for clarity.
   * debian/symbols: Bump the minimal version for lzma_code(),
     lzma_raw_buffer_decode(), and lzma_raw_buffer_encode().
   * Use machine-readable copyright-format 1.0.
   * Update copyright file.
   * Standards-Version: 3.9.3 (checked).
   * debian/ Use ‘git rev-list | git diff-tree’
     instead of ‘git log’ to avoid depending on the build system’s


xz-utils (5.1.1alpha+20110809-3) unstable; urgency=low

   * liblzma: Match upstream ABI.
     - Remove the lzma_chunk_size() function.
     - A few ABI tweaks to reserved space in structures.
     - Enable ELF symbol versioning.
     - Bump soname to 5.
     - Continue to leave out threading support, since the relevant
       interfaces in liblzma are not yet stable.
   * xz-utils/README.Debian: Remove note on ABI differences.
   * Remove liblzma/README.Debian.
   * liblzma: Introduce a lzma_code@Base compatibility symbol to ensure
     programs linked against unversioned symbols from liblzma2 can
     share a process image with liblzma5 without breaking.
   * debian/symbols: XZ_5.0 symbols come from liblzma5.  Build-Depends:
     dpkg-dev (>= 1.15.6); thanks to Jakub Wilk for a reminder.
   * debian/symbols: The lzma_code@Base symbol is not guaranteed to
     continue to exist in the future, so tell dpkg-shlibdeps to produce
     an error if some package manages to use it.

xz-utils (5.1.1alpha+20110809-2) unstable; urgency=low

   * debian/rules build-arch: Do not trigger an infinite "make"
     recursion loop when DEB_BUILD_OPTIONS=nocheck.  Closes: #638071.
     Thanks to Thorsten Glaser.

xz-utils (5.1.1alpha+20110809-1) unstable; urgency=low

   * New snapshot, taken from upstream commit 5c5b225.
     - liblzma:
       - lzma_stream_encoder() leaked memory.
       - The LZMA2 decoder rejected streams that decompress to a
         zero-length string.
       - lzma_easy_buffer_encode() and lzma_stream_buffer_encode()
         used to write such streams when asked to compress a 0-length
       - lzma_index_init() would segfault on allocation failure.
       - liblzma: Various functions check their arguments (especially
         choice of integrity check) better, making it harder to create
         a corrupt .xz file instead of receiving an error.
     - xz and scripts:
       - "xz -v -v --list" would read and try to free() uninitialized
         memory, continuing past the end of an on-stack array, when
         asked to describe certain corrupted XZ files.
       - xz -S.suf now refuses to compress a file whose name already
         ends with the suffix “.suf”.
       - xz --force can be used to compress setuid, setgid, sticky,
         and multiply linked files.
       - xz uses posix_fadvise() to speed up sequential input.
       - xz --block-size forces a full flush periodically during
         compression, for better random-access reading support and to
         make simple parallelism possible in the future.
       - unxz: The new --single-stream option discards trailing
         garbage after the end of the first stream.
       - xzdiff can read gzip- and bzip2-compressed files.
       - xzdiff and xzgrep can read lzop-compressed files.
       - xzegrep and xzfgrep perform extended regex and fixed-string
         matches, respectively.  (The previous behavior was to always
         use basic regexes.)
       - xzgrep -l (= --files-with-match) works.
       - The Czech “xz --help” output uses a more correct term for
         files with holes.  Thanks to Petr Hubený.  Closes: #605762.
       - xz: New Polish and French translations.
     - The Doxygen-generated documentation uses short, relative paths
       to name source files.  Closes: #572273.
   * Update copyright file.
   * Remove example programs from debian/examples.  They are included
     in the upstream source package now.
   * Move liblzma to an architecture-specific directory, so the
     native library and foreign-architecture versions can be installed
     - liblzma2: Pre-Depends: multiarch-support.
     - Use debhelper compatibility level 9.  This requires passing
       the dh sequence name before other options when invoking dh in
       debian/rules.  Build-Depends: debhelper (>= 8.1.3).
     - liblzma2, liblzma-dev: Install files under /usr/lib/<triplet>
       instead of /usr/lib.
     - Thanks to Steve Langasek for explaining the process on the
       Debian wiki.
   * Standards-Version: 3.9.2 (checked).
   * debian/control: liblzma2 is Multi-Arch: same, while xz-utils
     and xzdec are Multi-Arch: foreign.  Closes: #637883.  Thanks to
     Riku Voipio.
   * debian/symbols: Bump the minimal version for LZMA2 encoder
     functions that reject more bad arguments and skip empty blocks.
   * debian/rules: ./configure --disable-symbol-versions for now.
   * debian/rules: Provide build-arch and build-indep targets that
     only build the code and the API documentation, respectively.
     Thanks to Roger Leigh for suggesting it through lintian.
     Build-Depends: debhelper (>= 8.9.0).
   * debian/rules: Treat DEB_BUILD_OPTIONS=nocheck as a request not to
     run build-time tests.  Thanks to Thorsten Glaser for a reminder.
     Closes: #627209.


xz-utils (5.0.0-2) unstable; urgency=low

   * Upload to unstable.
   * liblzma2, liblzma-dev, xz-lzma: Install release notes.
   * debian/symbols: Bump the minimal versions for lzma_index_encoder,
     lzma_index_decoder to the version in which they gained LZMA_FINISH
   * xz-utils/README.Debian: Document differences from upstream ABI.
   * debian/ Avoid empty changelog entries when
     multiple Debian revisions match an upstream tag.

xz-utils (5.0.0-1) experimental; urgency=low

   * Upload to experimental.
   * New stable upstream release.  Closes: #592298.
     - xz avoids SA_RESTART.  This should not have a visible effect
       because xz already blocked signals during operations that
       would be difficult to resume after interruption.
     - liblzma: The coders returned by lzma_index_encoder() and
       lzma_index_decoder() support an LZMA_FINISH action, with
       identical semantics to LZMA_RUN.
     - The printable (PDF and PS) versions of the manual are easier
       to read.
     - Many documentation and build system cleanups.
   * liblzma: Back out upstream ABI tweaks.
   * liblzma/README.Debian: Document ABI differences from upstream.
   * Copy sample code not included in the release tarball from
     the development upstream repository to debian/examples.
   * debian/rules clean: Remove some files not included in the
     release tarball.
   * copyright: List new INSTALL.generic license.
   * debian/rules clean: Take new build-aux scripts into account.
   * debian/rules:  Adapt for upstream build system changes.
     Closes: #540443.
   * xz-utils, xzdec: Install release notes.

xz-utils (4.999.9beta+20100927-1) experimental; urgency=low

   * New snapshot, taken from upstream commit cec0ddc.
     - liblzma: The meaning of --extreme has been tweaked to address
       cases in which it made the compression ratio worse.  Some files
       might benefit slightly less from --extreme.
     - xz: Table columns are not misaligned any more in messages with
       multi-byte characters (e.g., file sizes with LANG=fi_FI.UTF-8).
     - xz: New German and Italian translations.
     - Various documentation, message, and translation updates.
   * Update copyright file.
   * debian/rules get-orig-source: Update upstream Git URL.
   * xz-utils/README.Debian: Advertise XZ_DEFAULTS.

xz-utils (4.999.9beta+20100903-1) experimental; urgency=low

   * New snapshot, taken from upstream commit 373ee26.
     - liblzma: The settings for compression levels 0 through 5
       (used by xz -0/.../-5) have been tweaked.  This affects the
       speed, compression ratio, and memory usage at compression and
       decompression time.
     - Does not search so hard for a match when a low "nice match
       length" setting is specified without a depth.
     - xz: The -1/.../-9 preset options override any previously
       specified filters, rather than vice versa.  To mix presets
       with filter options, use the --lzma2=preset=n option.
     - xz: Warns about --memlimit-compress settings that result in
       compression settings changing even if no explicit -1/.../-9,
       --lzma1, or --lzma2 option was used.
     - "xz -v -v --compress" now prints an estimate of the memory
       required to decompress a file.
   * debian/copyright: Update upstream Git URL.
   * debian/ Permit terser changelog lines.
   * Standards-Version: 3.9.1 (checked).

xz-utils (4.999.9beta+20100810-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit d5653ba8a.
     - xz: The memory usage limiter is now disabled by default.
     - xz: Support for an XZ_DEFAULTS environment variable was added.
       It contains user-specific default settings, such as memory usage
       limits, and can be overridden by the command line and XZ_OPT.
     - xz: The new --memlimit-compress and --memlimit-decompress
       options allow the memory usage limit to be set separately for
       compression and decompression.  A new --memlimit alias has been
       added for the existing --memory option.
     - xz: The --info-memory option (with or without --robot) now prints
       how much RAM is installed in addition to the compression and
       decompression memory limits.
   * liblzma-doc: Simplify package description.
   * debian/control: Build-Depends: autopoint | gettext (<< 0.18-1),
     autopoint | cvs instead of autopoint, to help with backporting.
     Thanks to Thorsten Glaser for a report.

xz-utils (4.999.9beta+20100713-1) unstable; urgency=low

   [ Thorsten Glaser ]
   * Explicitly depend on autoconf (>= 2.64~) due to AC_PREREQ,
     discovered during backporting.
   [ Jonathan Nieder ]
   * Upload to unstable.
   * New upstream snapshot, taken from upstream commit a540198f.
     - xz: The new --no-adjust option can be used to error out if there
       is insufficient memory for the chosen compression level.
   * liblzma-dev: Install examples to /usr/share/doc/liblzma-dev.
   * Update copyright file.
   * Drop unpack-time conflicts in favor of configuration-time
     conflicts (Replaces + Breaks):
      - xz-utils: against old xz-lzma (for lzmainfo).
      - xzdec: against old xz-lzma (for lzmadec).
      - xz-lzma: against lzip 1.7 (for lzdiff and lzgrep).
   * Standards-Version: 3.9.0.
   * debian/ Don’t regenerate upstream changelog when it is
     not out of date.
   * debian/rules get-orig-source: Use gzip --no-name --rsyncable.

xz-utils (4.999.9beta+20100602-1) experimental; urgency=low

   * New upstream snapshot, taken from upstream commit d8b41eed.
     - The output from "xz -v --list" and "xz -v -v --list" has been
       "xz -v -v --list" can be used to obtain an estimate for the memory
       required to decompress a file.
     - The xz manual page has some new material, including examples.
       Closes: #578465.
     - liblzma: The lzma_block_compressed_size() function no longer
       returns LZMA_DATA_ERROR for valid Blocks.
   * debian/symbols: Bump minimal version for lzma_block_compressed_size.
   * Correct the 4.999.9beta+20100307-1 changelog entry to describe
     which public functions were affected.
   * Add new xz-lzma package to allow xz to provide lzma and related
     commands.  Conflicts: and Provides: lzma.
   * xz-utils: Suggests: xz-lzma.
   * xz-utils/README.Debian: Take xz-lzma into account.

xz-utils (4.999.9beta+20100527-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit a334348dc.
     - Show both elapsed time and estimated remaining time in xz -v.
       Thanks to Trent W. Buck for the idea.  Closes: #574583.
     - liblzma: Remove the Subblock filter from the public API
       (the ABI is unchanged).
   * liblzma-dev.NEWS: Update.
   * xz-utils: Update Czech translation.
   * Change priority of xz-utils and liblzma2 to required and
     xzdec to extra.

xz-utils (4.999.9beta+20100307-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit f4b2b526.
     - liblzma: The stream initialization functions were not correctly
       initializing the internal allow_buffer_error flag.  As a result,
       ever since 4.999.9beta-1 in rare circumstances when decompressing
       LZMA files, the xz tool would produce spurious "Unexpected end
       of input" failures (Gentoo bug 305591).
     - The default memory usage limit on low-memory systems has been
   * debian/copyright: Clarify.

xz-utils (4.999.9beta+20100212-4) unstable; urgency=low

   * debian/control: Build-Depends: autopoint instead of cvs.
     Closes: #572481.
   * debian/copyright: Clean up and include more details.
   * debian/rules get-orig-source: Unindent comment lines.
   * xz-utils: include Czech translation.

xz-utils (4.999.9beta+20100212-3) unstable; urgency=low

   * liblzma-dev: Remove unneeded .la file.
   * xz-utils: Dynamically link the xz binary.
   * Do not waste time installing and running doxygen on buildds that
     are not going to build arch-all packages.
     Build-Depends-Indep: doxygen.  Closes: #540444.

xz-utils (4.999.9beta+20100212-2) unstable; urgency=low

   * Split off xzdec and lzmadec commands into new xzdec package.
     Thanks to Guillem Jover for the idea.  Closes: #571060.
   * xz-utils.NEWS: advertise this change.

xz-utils (4.999.9beta+20100212-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit eb7d51a3f.
      - xz --force compresses symlinks without complaint now.
      - liblzma: the optimized CRC32 implementation for x86 no longer
        misdetects the Hurd as Mac OS X.
   * debian/rules: ./configure --enable-assembler on the Hurd.
   * xz-utils: Simplify NEWS.Debian.gz.
   * liblzma-dev: Add a NEWS file to keep track of future API changes.
   * Drop unnecessary build-time conflict with autoconf2.13.
   * Add a blank line to the end of all NEWS files.
     (Works around: #247356)
   * debian/README.source: Leave out “-I -i” options.  Ignoring version
     control cruft is the default behavior with dpkg source format 3.0.
   * debian/ Pass ‘git log’ an explicit --format
     option to avoid problems if format.pretty is set in gitconfig.
   * Correct the 4.999.9beta+20100117-1 changelog entry.  It said:
      + The user-specified memory usage limit was not being honored in
        some cases.
     No such bug was observed, so describe the change instead.

xz-utils (4.999.9beta+20100131-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit f9dd797a.
      + xz: the --list option to display information about a compressed
        file (e.g., its uncompressed size) is now functional.  The output
        of the xz --robot --list command still may change in future
   * xz-utils: NEWS.Debian.gz: Clarify how interleaved output can
     go wrong.
   * debian/rules: Simplify:
      - remove support for comma as a delimiter for $(DEB_BUILD_OPTIONS).
      - rely on dh --parallel instead of tricky logic of our own to
        handle parallel builds.  Build-Depends: debhelper (>= 7.4.10).
   * Correct some typos in the 4.999.9beta+20100117-1 changelog entry.
   * Standards-Version: 3.8.4 (checked).
   * Update copyright file.

xz-utils (4.999.9beta+20100117-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit 07a11dad.
      + Fix some logic errors in the internal memory usage configuration
      + xz will no longer compress or decompress special files in place,
        even with --force.
        --force still enables compression of the target of a symlink.
      + xz will no longer read compressed data from a terminal or write
        it to a terminal, even with --force.
      + liblzma: many Index handling API improvements:
         - An lzma_index includes more useful metadata that is not
           actually from the Index.  This is particularly helpful for
           describing multiple-stream files.
            * lzma_index_cat() does not take a stream padding argument
              any more; use lzma_index_stream_padding() instead.
            * lzma_index_memusage() takes two arguments now.
              The new lzma_index_memused() convenience function
              calculates the total memory usage of an lzma_index.
            * lzma_index_count() has been replaced with
              lzma_index_block_count() and lzma_index_stream_count().
            * The new lzma_index_stream_flags() allows storing Stream
              Flags (e.g., checksum types) with the Index information.
            * The new lzma_index_checks() function indicates the list of
              checksum types in use.
            * lzma_index_equal() has been removed.  Its semantics were
              unclear, and something approximately equivalent can be
              implemented by iterating over Blocks in application code.
         - An lzma_index no longer represents a position within an Index.
           The new lzma_index_iter type can be used for that purpose.
            * Certain functions generate an iterator on demand now rather
              than clobbering their lzma_index arguments.  Using a single
              lzma_index for multiple concurrent invocations is safe now:
               lzma_index_buffer_encode(), lzma_index_encoder()
            * Functions that used to specify a Record by modifying an
              lzma_index argument have been renamed and taught to write
              an lzma_index_iter instead:
               lzma_index_locate() -> lzma_index_iter_locate()
               lzma_index_rewind() -> lzma_index_iter_rewind()
               lzma_index_read() -> lzma_index_iter_next()
            * The lzma_index_record type used by lzma_index_read() for
              complex seeks is no more.  lzma_index_iter_next() instead
              takes a parameter of the new lzma_index_iter_mode type.
            * New function: lzma_index_iter_init()
            * lzma_index_init() cannot reuse memory from an existing
              lzma_index any more.  The signature changed accordingly.
      + xz: support for decompressing to a sparse file
         - Try to write a sparse file if the decompressed stream contains
           long runs of null bytes.
         - The new --no-sparse option disables this behavior.
      + xz: add Czech translation.
      + liblzma-dev: lzma_filters_copy() and lzma_filters_update() are
        declared not to throw exceptions.
   * liblzma: bump soname.
   * xz-utils: Add NEWS.Debian describing the sparse file support.
   * debian/rules: Stop explicitly disabling assembler optimizations on
     the Hurd.  The configure script will check if a platform is
   * debian/rules: Update clean target to handle comments and wildcards
     in .gitignore.
   * Build-Depends: perl.
   * debian/rules: Speed up build by using autoreconf --symlink.
   * Remove debian/dirs lists.
   * Update copyright file and fix a small typo.


xz-utils (4.999.9beta+20091116-1) unstable; urgency=low

   * New upstream snapshot, taken from upstream commit d315ca4.
      + liblzma: add some new functions:
         - lzma_filters_copy() to copy a filter chain;
         - lzma_filters_update() to change compression options mid-stream;
         - lzma_physmem() to retrieve the total quantity of installed RAM.
      + Fix a design error in liblzma API.
         - Stop requiring caller to maintain filter chain during
           compression.  The library used to read it for new compression
           options.  Callers that need to change options mid-stream should
           use lzma_filters_update() instead.
         - Remove 'persistent' member from struct lzma_options_lzma.
      + xz: add --robot --info-memory options, for front-ends to use to
        read the memory usage limit.
   * liblzma: bump soname; add README.Debian explaining why soname
     differs from upstream.
   * Use source format 3.0 (quilt).
   * Update and clarify copyright file.

xz-utils (4.999.8beta-1) experimental; urgency=low

   [ Jonathan Nieder ]
   * Initial package for Debian. (Closes: #518803)
      + debian/rules:
         - add minimal rules file (using Debhelper 7), a control file
           describing the binary packages, and an appropriate compat file.
