Squashfs is a compressed read-only filesystem for Linux. Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed.
Multiple vulnerabilities have been discovered in SQUASHFS. Please review the CVE identifiers referenced below for details.
A remote attacker could entice a user to open a specially crafted .sqsh file using unsquashfs; possibly resulting in the execution of arbitrary code with the privileges of the process, or a Denial of Service condition.
There is no known workaround at this time.
All squashfs-tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-fs/squashfs-tools-4.3"
