    <p>
    Clam AntiVirus is a GPL anti-virus toolkit, designed for
    integration with mail servers to perform attachment scanning. Clam
    AntiVirus also provides a command line scanner and a tool for fetching
    updates of the virus database.

  <description>
    <p>
    Clam AntiVirus is vulnerable to a buffer overflow in
    "libclamav/upx.c" when processing malformed UPX-packed executables. It
    can also be sent into an infinite loop in "libclamav/fsg.c" when
    processing specially-crafted FSG-packed executables.
    </p>
  </description>
  <impact type="high">
    <p>
    By sending a specially-crafted file an attacker could execute
    arbitrary code with the permissions of the user running Clam AntiVirus,
    or cause a Denial of Service.
    </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 "&gt;=app-antivirus/clamav-0.87"</code>
  </resolution>
