    <p>
    Clam AntiVirus is a free anti-virus toolkit for UNIX, designed
    especially for e-mail scanning on mail gateways.

  <description>
    <p>
    Multiple vulnerabilities have been reported:
    </p>
    <ul>
    <li>
    Damian Put reported a heap-based buffer overflow when processing PeSpin
    packed PE binaries (CVE-2008-0314).
    </li>
    <li>
    Alin Rad Pop of Secunia Research reported a buffer overflow in the
    cli_scanpe() function when processing Upack PE binaries
    (CVE-2008-1100).
    </li>
    <li>
    Hanno Boeck reported an infinite loop when processing ARJ archives
    (CVE-2008-1387).
    </li>
    <li>
    Damian Put and Thomas Pollet reported a heap-based buffer overflow when
    processing WWPack compressed PE binaries (CVE-2008-1833).
    </li>
    <li>
    A buffer over-read was discovered in the rfc2231() function when
    producing a string that is not NULL terminated (CVE-2008-1836).
    </li>
    <li>
    An unspecified vulnerability leading to "memory problems" when scanning
    RAR files was reported (CVE-2008-1837).
    </li>
    <li>
    Thierry Zoller reported that scanning of RAR files could be
    circumvented (CVE-2008-1835).
    </li>
    </ul>
  </description>
  <impact type="high">
    <p>
    A remote attacker could entice a user or automated system to scan a
    specially crafted file, possibly leading to the execution of arbitrary
    code with the privileges of the user running ClamAV (either a system
    user or the "clamav" user if clamd is compromised), 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 "&gt;=app-antivirus/clamav-0.93"</code>
  </resolution>
