Synopsis
Multiple vulnerabilities have been discovered 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 sys-fs/squashfs-tools < 4.3-r1 >= 4.3-r1
Impact
===== Remote attackers, by enticing a user to process a specially crafted SQUASHFS image, could execute arbitrary code with the privileges of the process.
Workaround
There is no known workaround at this time.
