  <description>
    <p>
    Moritz Jodeit reported an off-by-one error within the
    get_unicode_name() function in libclamav/vba_extract.c when processing
    VBA project files (CVE-2008-5050). Ilja van Sprundel reported an
    infinite recursion error within the cli_check_jpeg_exploit() function
    in libclamav/special.c when processing JPEG files (CVE-2008-5314).
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could send a specially crafted VBA or JPEG file to
    the clamd daemon, possibly resulting in the remote execution of
    arbitrary code with the privileges of the user running the application
    or a Denial of Service.
    </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 &quot;&gt;=app-antivirus/clamav-0.94.2&quot;</code>
  </resolution>
