<description>
<p>Two vulnerabilities have been discovered in GNU cpio:</p>
<ul>
<li>The list_file function in GNU cpio contains a heap-based buffer
overflow vulnerability (CVE-2014-9112)
</li>
<li>A directory traversal vulnerability has been found in GNU cpio
(CVE-2015-1197)
</li>
</ul>
</description>
<impact type="normal">
<p>A remote attacker may be able to entice a user to open a specially
crafted archive using GNU cpio, possibly resulting in execution of
arbitrary code, a Denial of Service condition, or overwriting arbitrary
files.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All GNU cpio users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-arch/cpio-2.11-r3"
</code>
</resolution>
