  <description>
    <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>
