  script_tag(name:"insight", value:"This update for squashfs fixes the following issues:

  * CVE-2015-4645, CVE-2015-4646: Multiple buffer overflows fixed in squashfs-
      tools (bsc#935380)

  * CVE-2021-40153: Fixed an issue where an attacker might have been able to
      write a file outside of destination (bsc#1189936)

  * CVE-2021-41072: Fixed an issue where an attacker might have been able to
      write a file outside the destination directory via a symlink (bsc#1190531).

  update to 4.6.1:

  * Race condition which can cause corruption of the 'fragment table' fixed.
      This is a regression introduced in August 2022, and it has been seen when
      tailend packing is used (-tailends option).

  * Fix build failure when the tools are being built without extended attribute
      (XATTRs) support.

  * Fix XATTR error message when an unrecognised prefix is found

  * Fix incorrect free of pointer when an unrecognised XATTR prefix is found.

  * Major improvements in extended attribute handling, pseudo file handling, and
      miscellaneous new options and improvements

  * Extended attribute handling improved in Mksquashfs and Sqfstar

  * New Pseudo file xattr definition to add extended attributes to files.

  * New xattrs-add Action to add extended attributes to files

  * Extended attribute handling improved in Unsquashfs

  * Other major improvements

  * Unsquashfs can now output Pseudo files to standard out.

  * Mksquashfs can now input Pseudo files from standard in.

  * Squashfs filesystems can now be converted (different block size compression
      etc) without unpacking to an intermediate filesystem or mounting, by piping
      the output of Unsquashfs to Mksquashfs.

  * Pseudo files are now supported by Sqfstar.

  * 'Non-anchored' excludes are now supported by Unsquashfs.

  update to 4.5.1 (bsc#1190531, CVE-2021-41072):

  * This release adds Manpages for Mksquashfs(1), Unsquashfs(1), Sqfstar(1) and
      Sqfscat(1).

  * The -help text output from the utilities has been improved and extended as
      well (but the Manpages are now more comprehensive).

  * CVE-2021-41072 which is a writing outside of destination exploit, has been
      fixed.

  * The number of hard-links in the filesystem is now also displayed by
      Mksquashfs in the output summary.

  * The number of hard-links written by Unsquashfs is now also displayed in the
      output summary.

  * Unsquashfs will now write to a pre-existing destination directory, rather
      than aborting.

  * Unsquashfs now a ...
