Synopsis
Multiple vulnerabilities have been found in SQUASHFS, the worst of which may allow execution of arbitrary code.
Background
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.
Affected Packages
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 squashfs-tools < 4.3 >= 4.3
Impact
===== 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.
Workaround
There is no known workaround at this time.
