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
