Public bug reported:

Please sync xz-utils 5.6.1-1 (main) from Debian unstable (main)

Hello! I am one of the upstream maintainers for XZ Utils. Version 5.6.1
was recently released and uploaded to Debian as a bugfix only release.
Notably, this fixes a bug that causes Valgrind to issue a warning on
any application dynamically linked with liblzma. This includes a lot of
important applications. This could break build scripts and test
pipelines that expect specific output from Valgrind in order to pass.

Additionally, this fixes a small typo for the man pages translations
for Brazilian Portuguese, German, French, Korean, Romanian, and
Ukrainian, and removes the need for patches applied for version
5.6.0-0.2.

The other bugfixes in this release have no impact on Ubuntu. They
involve building with CMake or when building on a system without
Landlock system calls defined (these are defined in Ubuntu).

Changelog entries since current noble version 5.6.0-0.2:

xz-utils (5.6.1-1) unstable; urgency=medium

  * Non-maintainer upload.
  * Import 5.6.1 (Closes: #1067708).
  * Takeover maintenance of the package.

Excerpt from the NEWS entry from upstream:

5.6.1 (2024-03-09)

    * liblzma: Fixed two bugs relating to GNU indirect function (IFUNC)
      with GCC. The more serious bug caused a program linked with
      liblzma to crash on start up if the flag -fprofile-generate was
      used to build liblzma. The second bug caused liblzma to falsely
      report an invalid write to Valgrind when loading liblzma.

    * xz: Changed the messages for thread reduction due to memory
      constraints to only appear under the highest verbosity level.

    * Build:

        - Fixed a build issue when the header file <linux/landlock.h>
          was present on the system but the Landlock system calls were
          not defined in <sys/syscall.h>.

        - The CMake build now warns and disables NLS if both gettext
          tools and pre-created .gmo files are missing. Previously,
          this caused the CMake build to fail.

    * Minor improvements to man pages.

    * Minor improvements to tests.

** Affects: xz-utils (Ubuntu)
     Importance: Undecided
         Status: New
