- 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
