<p>
Two vulnerabilities were discovered:
</p>
<ul><li>
Simon Wilkinson discovered from a bug report by Toby Blake that the
cache manager of OpenAFS contains a heap-based buffer overflow which is
related to the use of the ERR_PTR macro (CVE-2009-1250).</li>
<li>A
pointer dereference bug when using XDR arrays was discovered by Simon
Wilkinson, with assistance from Derrick Brashear and Jeffrey Altman.
(CVE-2009-1251).</li>
</ul>
</description>
<impact type="normal">
<p>
The vulnerabilities might allow remote unauthenticated attackers to
cause a Denial of Service (system crash) and possibly execute arbitrary
code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All OpenAFS users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-fs/openafs-1.4.9"</code>
</resolution>
