<description>
<p>Multiple vulnerabilities have been discovered in MCrypt:</p>
<ul>
<li>A boundary error in MCrypt could cause a stack-based buffer overflow
(CVE-2012-4409).
</li>
<li>MCrypt contains multiple format string errors (CVE-2012-4426).</li>
<li>MCrypt does not properly handle long file names, which could cause a
stack-based buffer overflow (CVE-2012-4527).
</li>
</ul>
</description>
<impact type="normal">
<p>A remote attacker could entice a user to open a specially crafted file
using MCrypt, possibly resulting in 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 MCrypt users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-crypt/mcrypt-2.6.8-r2"
</code>
