Title:
  Sync xz-utils 5.6.1-1 (main) from Debian unstable (main)

Status in xz-utils package in Ubuntu:
  New

Bug description:
  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.
