<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 ">=app-crypt/mcrypt-2.6.8-r2"
|

</code>
