SQUASHFS: Multiple vulnerabilities — GLSA 201612-40

Multiple vulnerabilities have been found in SQUASHFS, the worst of which may allow execution of arbitrary code.

Affected packages

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.

Description

Multiple vulnerabilities have been discovered in SQUASHFS. Please review the CVE identifiers referenced below for details.

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.

Resolution

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=sys-fs/squashfs-tools-4.3"
