http://security.gentoo.org/

Severity:	normal
Title:	SQUASHFS: Multiple vulnerabilities
Date:	12/13/2016
Bugs:	#427356
ID:	201612-40

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	Architecture(s)
sys-fs/squashfs-tools	< 4.3	>= 4.3	All supported architectures

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

All squashfs-tools users should upgrade to the latest version:

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