    <p>
    Clam AntiVirus (short: ClamAV) is an anti-virus toolkit for UNIX,
    designed especially for e-mail scanning on mail gateways.
    </p>
  </background>
  <description>
    <p>
    Multiple vulnerabilities have been found in ClamAV:
    </p>
    <ul>
    <li>The
    vendor reported a Divide-by-zero error in the PE ("Portable
    Executable"; Windows .exe) file handling of ClamAV
    (CVE-2008-6680).</li>
    <li>Jeffrey Thomas Peckham found a flaw in
    libclamav/untar.c, possibly resulting in an infinite loop when
    processing TAR archives in clamd and clamscan (CVE-2009-1270).</li>
    <li>Martin Olsen reported a vulnerability in the CLI_ISCONTAINED macro
    in libclamav/others.h, when processing UPack archives
    (CVE-2009-1371).</li>
    <li>Nigel disclosed a stack-based buffer overflow
    in the "cli_url_canon()" function in libclamav/phishcheck.c when
    processing URLs (CVE-2009-1372).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to process a
    specially crafted UPack archive or a file containing a specially
    crafted URL, possibly resulting in the remote execution of arbitrary
    code with the privileges of the user running the application, or a
    Denial of Service. Furthermore, a remote attacker could cause a Denial
    of Service by supplying a specially crafted TAR archive or PE
    executable to a Clam AntiVirus instance.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Clam AntiVirus users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-antivirus/clamav-0.95.2&quot;</code>
  </resolution>
