An update that solves four vulnerabilities can now be installed.
## Description:
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 allows "." to used as the destination, to extract to the
current directory.
* The Unsquashfs progress bar now tracks empty files and hardlinks, in
addition to data blocks.
* -no-hardlinks option has been implemented for Sqfstar.
* More sanity checking for "corrupted" filesystems, including checks for
multiply linked directories and directory loops.
* Options that may cause filesystems to be unmountable have been moved into a
new "experts" category in the Mksquashfs help text (and Manpage).
* Maximum cpiostyle filename limited to PATH_MAX. This prevents attempts to
overflow the stack, or cause system calls to fail with a too long pathname.
* Don't always use "max open file limit" when calculating length of queues, as
a very large file limit can cause Unsquashfs to abort. Instead use the
smaller of max open file limit and cache size.
* Fix Mksquashfs silently ignoring Pseudo file definitions when appending.
* Don't abort if no XATTR support has been built in, and there's XATTRs in the
filesystem. This is a regression introduced in 2019 in Version 4.4.
* Fix duplicate check when the last file block is sparse.
update to 4.5:
* Mksquashfs now supports "Actions".
* New sqfstar command which will create a Squashfs image from a tar archive.
* Tar style handling of source pathnames in Mksquashfs.
* Cpio style handling of source pathnames in Mksquashfs.
* New option to throttle the amount of CPU and I/O.
* Mksquashfs now allows no source directory to be specified.
* New Pseudo file "R" definition which allows a Regular file o be created with
data stored within the Pseudo file.
* Symbolic links are now followed in extract files
* Unsquashfs now supports "exclude" files.
* Max depth traversal option added.
* Unsquashfs can now output a "Pseudo file" representing the input Squashfs
filesystem.
* New -one-file-system option in Mksquashfs.
* New -no-hardlinks option in Mksquashfs.
* Exit code in Unsquashfs changed to distinguish between non-fatal errors
(exit 2), and fatal errors (exit 1).
* Xattr id count added in Unsquashfs "-stat" output.
* Unsquashfs "write outside directory" exploit fixed.
* Error handling in Unsquashfs writer thread fixed.
* Fix failure to truncate destination if appending aborted.
* Prevent Mksquashfs reading the destination file.
