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
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 ">=squashfs-tools-4.3"
