<background>
<p>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.
</p>

<description>
<p>Multiple vulnerabilities have been discovered in SQUASHFS. Please review
the CVE identifiers referenced below for details.
</p>
</description>
<impact type="normal">
<p>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.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All squashfs-tools users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=sys-fs/squashfs-tools-4.3"
</code>
