    <p>
    Marc Merlin and John Dong reported multiple vulnerabilities in JHead:
    </p>
    <ul>
    <li>
    A buffer overflow in the DoCommand() function when processing the cmd
    argument and related to potential string overflows (CVE-2008-4575).
    </li>
    <li>
    An insecure creation of a temporary file (CVE-2008-4639).
    </li>
    <li>
    A error when unlinking a file (CVE-2008-4640).
    </li>
    <li>
    Insufficient escaping of shell metacharacters (CVE-2008-4641).
    </li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could possibly execute arbitrary code by enticing a
    user or automated system to open a file with a long filename or via
    unspecified vectors. It is also possible to trick a user into deleting
    or overwriting files.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All JHead users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/jhead-2.84-r1&quot;</code>
  </resolution>
