  <description>
    <p>
    Erik Sjolund discovered several issues in enscript: it suffers
    from several buffer overflows (CAN-2004-1186), quotes and shell escape
    characters are insufficiently sanitized in filenames (CAN-2004-1185),
    and it supported taking input from an arbitrary command pipe, with
    unwanted side effects (CAN-2004-1184).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could design malicious files or input data which, once
    feeded into enscript, would trigger the execution of arbitrary code
    with the rights of the user running enscript.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All enscript users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/enscript-1.6.3-r3&quot;</code>
  </resolution>
