* liblzma:
- Fix the build on ARM64 on glibc versions older than
2.24 (2016). They don't have HWCAP_CRC32 in <sys/auxv.h>.
- Disable CLMUL CRC code when building for 32-bit x86
with old MSVC versions. This avoids a compiler bug.
* xz:
- Add a workaround for Red Hat Enterprise Linux 9
kernel bug which made xz fail with "xz: Failed to enable the
sandbox".
- On AIX, don't use fsync() on directories because it
fails.
- Fix the build on Emscripten.
- Fix the build on clang-cl on Windows.
- Take resource limits (RLIMIT_DATA, RLIMIT_AS, and
RLIMIT_VMEM)
OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=173
- Update to 5.8.1:
* Multithreaded .xz decoder (lzma_stream_decoder_mt()):
- Fix a bug that could at least result in a crash with
invalid input. (bsc#1240414, CVE-2025-31115)
- Fix a performance bug: Only one thread was used if the whole
input file was provided at once to lzma_code(), the output
buffer was big enough, timeout was disabled, and LZMA_FINISH
was used. There are no bug reports about this, thus it's
possible that no real-world application was affected.
* Avoid <stdalign.h> even with C11/C17 compilers. This fixes the
build with Oracle Developer Studio 12.6 on Solaris 10 when the
compiler is in C11 mode (the header doesn't exist).
* Autotools: Restore compatibility with GNU make versions older
than 4.0 by creating the package using GNU gettext 0.23.1
infrastructure instead of 0.24.
* Update Croatian translation.
- 5.8.0 changelog:
* liblzma on 32/64-bit x86: When possible, use SSE2 intrinsics
instead of memcpy() in the LZMA/LZMA2 decoder. In typical cases,
this may reduce decompression time by 0-5 %. However, when built
against musl libc, over 15 % time reduction was observed with
highly compressed files.
* CMake: Make the feature test macros match the Autotools-based
build on NetBSD, Darwin, and mingw-w64.
* Update the Croatian, Italian, Portuguese, and Romanian
translations.
* Update the German, Italian, Korean, Romanian, Serbian, and
Ukrainian man page translations.
- Summary of changes in the 5.7.x development releases:
* Mark the following LZMA Utils script aliases as deprecated:

- Update to 5.6.3:
* liblzma:
- Fix x86-64 inline assembly compatibility with GNU Binutils
older than 2.27.
- Fix the build with GCC 4.2 on OpenBSD/sparc64.
* xzdec: Display an error instead of failing silently if the
unsupported option -M is specified.
* lzmainfo: Fix integer overflows when rounding the dictionary and
uncompressed sizes to the nearest mebibyte.
* Autotools-based build:
- Fix feature checks with link-time optimization (-flto).
- Solaris: Fix a compatibility issue in version.sh. It matters
if one wants to regenerate configure by running autoconf.
* CMake:
- Use paths relative to ${prefix} in liblzma.pc when possible.
This is done only with CMake >= 3.20.
- Prefer a C11 compiler over a C99 compiler but accept both.
- Link Threads::Threads against liblzma using PRIVATE so that
-pthread and such flags won't unnecessarily get included in
the usage requirements of shared liblzma. That is,
target_link_libraries(foo PRIVATE liblzma::liblzma) no
longer adds -pthread if using POSIX threads and linking
against shared liblzma. The threading flags are still added
if linking against static liblzma.
* Updated translations: Catalan, Chinese (simplified), and
Brazilian Portuguese.

- Update to 5.6.2:
* Remove the backdoor (CVE-2024-3094).
* Not changed: Memory sanitizer (MSAN) has a false positive
in the CRC CLMUL code which also makes OSS Fuzz unhappy.
Valgrind is smarter and doesn't complain.
A revision to the CLMUL code is coming anyway and this issue
will be cleaned up as part of it. It won't be backported to
5.6.x or 5.4.x because the old code isn't wrong. There is
no reason to risk introducing regressions in old branches
just to silence a false positive.
* liblzma:
- lzma_index_decoder() and lzma_index_buffer_decode(): Fix
a missing output pointer initialization (*i = NULL) if the
functions are called with invalid arguments. The API docs
say that such an initialization is always done. In practice
this matters very little because the problem can only occur
if the calling application has a bug and these functions
return LZMA_PROG_ERROR.
- lzma_str_to_filters(): Fix a missing output pointer
initialization (*error_pos = 0). This is very similar
to the fix above.
- Fix C standard conformance with function pointer types.
- Remove GNU indirect function (IFUNC) support. This is *NOT*
done for security reasons even though the backdoor relied on
this code. The performance benefits of IFUNC are too tiny in
this project to make the extra complexity worth it.
- FreeBSD on ARM64: Add error checking to CRC32 instruction
support detection.
- Fix building with NVIDIA HPC SDK.

* Fixed a bug involving internal function pointers in liblzma
not being initialized to NULL. The bug can only be
triggered if lzma_filters_update() is called on a LZMA1
encoder, so it does not affect xz or any application known
to us that uses liblzma.
* Fixed a regression introduced in 5.4.2 that caused
encoding in the raw format to unnecessarily fail if --suffix
was not used. For instance, the following command no longer
reports that --suffix must be used:
echo foo | xz --format=raw --lzma2 | wc -c
* Fixed an issue on MinGW-w64 builds that prevented
reading from or writing to non-terminal character devices
like NUL.
* Added a new test.
- Build XZ with full RELRO.
- Put libraries back in %{_libdir}, /usr merge project.
- Fix build in armv5el doesnt like profiling
* Polish translation was added.
* Support for "xz --list" was added

- Fixed an assertion failure that could be triggered by a large
unpadded_size argument. It was verified that there was no
other bug than the assertion failure.
- Fixed a bug that prevented building with Windows Vista
threading when __attribute__((__constructor__)) is not
supported.
* xz now properly handles special files such as "con" or "nul" on
Windows. Before this fix, the following wrote "foo" to the
console and deleted the input file "con_xz":
echo foo | xz > con_xz
xz --suffix=_xz --decompress con_xz
* Small fixes and improvements to the tests.
* Updated translations: Chinese (simplified) and Esperanto.

- Update to version 5.4.2:
* All fixes from 5.2.11 that were not included in 5.4.1.
* If xz is built with support for the Capsicum sandbox but running
in an environment that doesn't support Capsicum, xz now runs
normally without sandboxing instead of exiting with an error.
* liblzma:
- Documentation was updated to improve the style, consistency,
and completeness of the liblzma API headers.
- The Doxygen-generated HTML documentation for the liblzma API
header files is now included in the source release and is
installed as part of "make install". All JavaScript is
removed to simplify license compliance and to reduce the
install size.
- Fixed a minor bug in lzma_str_from_filters() that produced
too many filters in the output string instead of reporting
an error if the input array had more than four filters. This
bug did not affect xz.
* Build systems:
- autogen.sh now invokes the doxygen tool via the new wrapper
script doxygen/update-doxygen, unless the command line option
--no-doxygen is used.
- Added microlzma_encoder.c and microlzma_decoder.c to the
VS project files for Windows and to the CMake build. These
should have been included in 5.3.2alpha.
* Tests:
- Added a test to the CMake build that was forgotten in the
previous release.
- Added and refactored a few tests.
* Translations:
- Updated the Brazilian Portuguese translation.

* liblzma:
- Fixed the return value of lzma_microlzma_encoder() if the
LZMA options lc/lp/pb are invalid. Invalid lc/lp/pb options
made the function return LZMA_STREAM_END without encoding
anything instead of returning LZMA_OPTIONS_ERROR.
* Tests:
- Fixed test script compatibility with ancient /bin/sh
versions. Now the five test_compress_* tests should
no longer fail on Solaris 10.
- Added and refactored a few tests.
* Translations:
- Updated the Catalan and Esperanto translations.
- Added Korean and Ukrainian man page translations.

- update to 5.4.0:
This bumps the minor version of liblzma because new features were
added. The API and ABI are still backward compatible with liblzma
5.2.x and 5.0.x.
Summary of new features added in the 5.3.x development releases:
* liblzma:
- Added threaded .xz decompressor lzma_stream_decoder_mt().
It can use multiple threads with .xz files that have multiple
Blocks with size information in Block Headers. The threaded
encoder in xz has always created such files.
Single-threaded encoder cannot store the size information in
Block Headers even if one used LZMA_FULL_FLUSH to create
multiple Blocks, so this threaded decoder cannot use multiple
threads with such files.
If there are multiple Streams (concatenated .xz files), one
Stream will be decompressed completely before starting the
next Stream.
- A new decoder flag LZMA_FAIL_FAST was added. It makes the
threaded decompressor report errors soon instead of first
flushing all pending data before the error location.
- New Filter IDs:
* LZMA_FILTER_ARM64 is for ARM64 binaries.
* LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don't
necessarily use the end marker.
- Added lzma_str_to_filters(), lzma_str_from_filters(), and
lzma_str_list_filters() to convert a preset or a filter chain
string to a lzma_filter[] and vice versa. These should make
it easier to write applications that allow users to specify
custom compression options.
- Added lzma_filters_free() which can be convenient for freeing
OBS-URL: https://build.opensuse.org/request/show/1045839
OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=123
- update to 5.2.10:
* xz: Don't modify argv[] when parsing the --memlimit* and
--block-list command line options. This fixes confusing
arguments in process listing (like "ps auxf").
* GNU/Linux only: Use __has_attribute(__symver__) to detect if
that attribute is supported. This fixes build on Mandriva where
Clang is patched to define __GNUC__ to 11 by default (instead
of 4 as used by Clang upstream).
* liblzma:
- Fixed an infinite loop in LZMA encoder initialization
if dict_size >= 2 GiB.
- Fixed two cases of invalid free() that can happen if
a tiny allocation fails in encoder re-initialization
or in lzma_filters_update(). These bugs had some
similarities with the bug fixed in 5.2.7.
- Fixed lzma_block_encoder() not allowing the use of
LZMA_SYNC_FLUSH with lzma_code() even though it was
documented to be supported. The sync-flush code in
the Block encoder was already used internally via
lzma_stream_encoder(), so this was just a missing flag
in the lzma_block_encoder() API function.
- GNU/Linux only: Don't put symbol versions into static
liblzma as it breaks things in some cases (and even if
it didn't break anything, symbol versions in static
libraries are useless anyway). The downside of the fix
is that if the configure options --with-pic or --without-pic
are used then it's not possible to build both shared and
static liblzma at the same time on GNU/Linux anymore;
with those options --disable-static or --disable-shared
must be used too.
OBS-URL: https://build.opensuse.org/request/show/1043472
OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=121
- Update to 5.2.8:
* xz:
- If xz cannot remove an input file when it should, this
is now treated as a warning (exit status 2) instead of
an error (exit status 1). This matches GNU gzip and it
is more logical as at that point the output file has
already been successfully closed.
- Fix handling of .xz files with an unsupported check type.
Previously such printed a warning message but then xz
behaved as if an error had occurred (didn't decompress,
exit status 1). Now a warning is printed, decompression
is done anyway, and exit status is 2. This used to work
slightly before 5.0.0. In practice this bug matters only
if xz has been built with some check types disabled. As
instructed in PACKAGERS, such builds should be done in
special situations only.
- Fix "xz -dc --single-stream tests/files/good-0-empty.xz"
which failed with "Internal error (bug)". That is,
--single-stream was broken if the first .xz stream in
the input file didn't contain any uncompressed data.
- Fix displaying file sizes in the progress indicator when
working in passthru mode and there are multiple input files.
Just like "gzip -cdf", "xz -cdf" works like "cat" when the
input file isn't a supported compressed file format. In
this case the file size counters weren't reset between
files so with multiple input files the progress indicator
displayed an incorrect (too large) value.
* liblzma:
- API docs in lzma/container.h:
* Update the list of decoder flags in the decoder
OBS-URL: https://build.opensuse.org/request/show/1036633
OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=117
- update to 5.2.7:
* liblzma:
- Add API doc note about the .xz decoder LZMA_MEMLIMIT_ERROR bug.
- Add dest and src NULL checks to lzma_index_cat.
The documentation states LZMA_PROG_ERROR can be returned from
lzma_index_cat. Previously, lzma_index_cat could not return
LZMA_PROG_ERROR. Now, the validation is similar to
lzma_index_append, which does a NULL check on the index
parameter.
- Fix copying of check type statistics in lzma_index_cat().
The check type of the last Stream in dest was never copied to
dest->checks (the code tried to copy it but it was done too late).
This meant that the value returned by lzma_index_checks() would
only include the check type of the last Stream when multiple
lzma_indexes had been concatenated.
In xz --list this meant that the summary would only list the
check type of the last Stream, so in this sense this was only
a visual bug. However, it's possible that some applications
use this information for purposes other than merely showing
it to the users in an informational message. I'm not aware of
such applications though and it's quite possible that such
applications don't exist.
Regular streamed decompression in xz or any other application
doesn't use lzma_index_cat() and so this bug cannot affect them.
- Stream decoder: Fix restarting after LZMA_MEMLIMIT_ERROR.
If lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible
to use lzma_memlimit_set() to increase the limit and continue
decoding. This was supposed to work from the beginning but
there was a bug. With other decoders (.lzma or threaded .xz)
this already worked correctly.
- lzma_filters_copy: Keep dest[] unmodified if an error occurs.
lzma_stream_encoder() and lzma_stream_encoder_mt() always assumed
this. Before this patch, failing lzma_filters_copy() could result
in free(invalid_pointer) or invalid memory reads in stream_encoder.c
or stream_encoder_mt.c.
To trigger this, allocating memory for a filter options structure
has to fail. These are tiny allocations so in practice they very
rarely fail.
Certain badness in the filter chain array could also make
lzma_filters_copy() fail but both stream_encoder.c and
stream_encoder_mt.c validate the filter chain before
trying to copy it, so the crash cannot occur this way.
- lzma_index_append: Add missing integer overflow check.
The documentation in src/liblzma/api/lzma/index.h suggests that
both the unpadded (compressed) size and the uncompressed size
are checked for overflow, but only the unpadded size was checked.
The uncompressed check is done first since that is more likely to
occur than the unpadded or index field size overflows.
- Vaccinate against an ill patch from RHEL/CentOS 7.
* xzgrep:
- Fix compatibility with old shells.
Turns out that some old shells don't like apostrophes (') inside
command substitutions. The problem was introduced by commits
69d1b3fc29677af8ade8dc15dba83f0589cb63d6 (2022-03-29),
bd7b290f3fe4faeceb7d3497ed9bf2e6ed5e7dc5 (2022-07-18), and
a648978b20495b7aa4a8b029c5a810b5ad9d08ff (2022-07-19).
5.2.6 is the only stable release that included
this problem.
* Translations: Add Turkish translation.

OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=113
- update to 5.2.6 (CVE-2022-1271, bsc#1198062):
* xz:
- The --keep option now accepts symlinks, hardlinks, and
setuid, setgid, and sticky files.
- When copying metadata from the source file to the destination
file, don't try to set the group (GID) if it is already set
correctly. This avoids a failure on OpenBSD (and possibly on
a few other OSes) where files may get created so that their
group doesn't belong to the user, and fchown(2) can fail even
if it needs to do nothing.
- Cap --memlimit-compress to 2000 MiB instead of 4020 MiB on
MIPS32 because on MIPS32 userspace processes are limited
to 2 GiB of address space.
* liblzma:
- Fixed a missing error-check in the threaded encoder. If a
small memory allocation fails, a .xz file with an invalid
Index field would be created. Decompressing such a file would
produce the correct output but result in an error at the end.
Thus this is a "mild" data corruption bug. Note that while
a failed memory allocation can trigger the bug, it cannot
cause invalid memory access.
- The decoder for .lzma files now supports files that have
uncompressed size stored in the header and still use the
end of payload marker (end of stream marker) at the end
of the LZMA stream. Such files are rare but, according to
the documentation in LZMA SDK, they are valid.
doc/lzma-file-format.txt was updated too.
- Improved 32-bit x86 assembly files:
* Support Intel Control-flow Enforcement Technology (CET)
* Use non-executable stack on FreeBSD.
OBS-URL: https://build.opensuse.org/request/show/994818
OBS-URL: https://build.opensuse.org/package/show/Base:System/xz?expand=0&rev=111
- Update to 5.2.5:
* liblzma:
- Fixed several C99/C11 conformance bugs. Now the code is clean
under gcc/clang -fsanitize=undefined. Some of these changes
might have a negative effect on performance with old GCC
versions or compilers other than GCC and Clang. The configure
option --enable-unsafe-type-punning can be used to (mostly)
restore the old behavior but it shouldn't normally be used.
- Improved API documentation of lzma_properties_decode().
- Added a very minor encoder speed optimization.
* xz:
- Fixed a crash in "xz -dcfv not_an_xz_file". All four options
were required to trigger it. The crash occurred in the
progress indicator code when xz was in passthru mode where
xz works like "cat".
- Fixed an integer overflow with 32-bit off_t. It could happen
when decompressing a file that has a long run of zero bytes
which xz would try to write as a sparse file. Since the build
system enables large file support by default, off_t is
normally 64-bit even on 32-bit systems.
- Fixes for --flush-timeout:
* Fix semi-busy-waiting.
* Avoid unneeded flushes when no new input has arrived
since the previous flush was completed.
- Added a special case for 32-bit xz: If --memlimit-compress is
used to specify a limit that exceeds 4020 MiB, the limit will
be set to 4020 MiB. The values "0" and "max" aren't affected
by this and neither is decompression. This hack can be
helpful when a 32-bit xz has access to 4 GiB address space
but the specified memlimit exceeds 4 GiB. This can happen
e.g. with some scripts.
- Capsicum sandbox is now enabled by default where available
(FreeBSD >= 10). The sandbox debug messages (xz -vv) were
removed since they seemed to be more annoying than useful.

Hi Andreas,
thanks for catching the missed parts.
To be honest, I don't get the meaning of of the 2nd sentence of the

OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/xz?expand=0&rev=44
- Update to version 5.0.5
* lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
.lzma files that have less common settings in the headers
(dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
size greater than 256 GiB).
* xz:
- Fixes and improvements to error handling.
- Various fixes to the man page.
* xzless: Fixed to work with "less" versions 448 and later
* xzgrep: Made -h an alias for --no-filename.

- Update to version 5.0.4
* liblzma:
- Fix lzma_index_init(). It could crash if memory allocation
failed.
- Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
filter is used and the application only provides exactly as
much output space as is the uncompressed size of the file.
- Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
check if the last call to lzma_code() really returned
LZMA_STREAM_END, which made the program think that truncated
files are valid.
- New example programs in doc/examples (old programs are now in
doc/examples_old). These have more comments and more detailed
error handling.
* Fix "xz -lvv foo.xz". It could crash on some corrupted files.
* Fix output of "xz --robot -lv" and "xz --robot -lvv" which
incorrectly printed the filename also in the "foo (x/x)" format.
* Fix exit status of "xzdiff foo.xz bar.xz".
* Fix exit status of "xzgrep foo binary_file".
* Fix portability to EBCDIC systems.
* Fix a configure issue on AIX with the XL C compiler. See INSTALL
for details.
* Update French, German, Italian, and Polish translations (forwarded request 143030 from rudi_m)

- Update to version 5.0.3
* liblzma fixes:
- A memory leak was fixed.
- lzma_stream_buffer_encode() no longer creates an empty .xz
Block if encoding an empty buffer. Such an empty Block with
LZMA2 data would trigger a bug in 5.0.1 and older (see the
first bullet point in 5.0.2 notes). When releasing 5.0.2,
I thought that no encoder creates this kind of files but
I was wrong.
- Validate function arguments better in a few functions. Most
importantly, specifying an unsupported integrity check to
lzma_stream_buffer_encode() no longer creates a corrupt .xz
file. Probably no application tries to do that, so this
shouldn't be a big problem in practice.
- Document that lzma_block_buffer_encode(),
lzma_easy_buffer_encode(), lzma_stream_encoder(), and
lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
- The return values of the _memusage() functions are now
documented better.
* Fix command name detection in xzgrep. xzegrep and xzfgrep now
correctly use egrep and fgrep instead of grep.
* French translation was added.
