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

Description
===========

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

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.

Resolution
==========

All SQUASHFS users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=sys-fs/squashfs-tools-4.3-r1"
