* 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 ...
