    <p>
    Damian Put has discovered an out-of-bounds memory access while
    processing Petite files (CVE-2008-2713, CVE-2008-3215). Also, please
    note that the 0.93 ClamAV branch fixes the first of the two attack
    vectors of CVE-2007-6595 concerning an insecure creation of temporary
    files vulnerability. The sigtool attack vector seems still unfixed.
    </p>
  </description>
  <impact type="low">
    <p>
    A remote attacker could entice a user or automated system to scan a
    specially crafted Petite file, possibly resulting in a Denial of
    Service (daemon crash). Also, the insecure creation of temporary files
    vulnerability can be triggered by a local user to perform a symlink
    attack.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ClamAV users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-antivirus/clamav-0.93.3"</code>
  </resolution>
