  <description>
    <p>
    Comix does not properly sanitize filenames containing shell
    metacharacters when they are passed to the rar, unrar, or jpegtran
    programs (CVE-2008-1568). Comix also creates directories with
    predictable names (CVE-2008-1796).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit the first vulnerability by enticing a
    user to use Comix to open a file with a specially crafted filename,
    resulting in the execution of arbitrary commands. The second
    vulnerability could be exploited by a local attacker to cause a Denial
    of Service by creating a file or directory with the same filename as
    the predictable filename used by Comix.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Comix users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/comix-3.6.4-r1&quot;</code>
  </resolution>
