  <description>
    <p>
    Two stack-based buffer overflows in the read_special_escape() function
    in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research
    discovered a vulnerability related to the "setfilename" command
    (CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability
    related to the "font" escape sequence (CVE-2008-4306).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice a user or automated system to process
    specially crafted input with the special escapes processing enabled
    using the "-e" option, possibly resulting in the execution of arbitrary
    code.
    </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 "&gt;=app-text/enscript-1.6.4-r4"</code>
  </resolution>
