SQUASHFS: Multiple vulnerabilities

SQUASHFS: Multiple vulnerabilities Multiple vulnerabilities have been found in SQUASHFS, the worst of which may allow execution of arbitrary code. squashfs-tools 2016-12-13 2016-12-14 427356 remote 4.3 4.3

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"
