  <description>
    <p>Multiple vulnerabilities have been discovered in SWI-Prolog:
      * An error in the canoniseFileName() function could cause a stack-based
      buffer overflow (CVE-2012-6089).
      * An error in the expand() function could cause a stack-based buffer
      overflow (CVE-2012-6090).
    </p>
  </description>
  <impact type="normal">
    <p>A context-dependent attack can create files with specially crafted
      names, causing arbitrary code execution or a denial of service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All SWI-Prolog users should upgrade to the latest version:</p>

      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-lang/swi-prolog-6.2.5"
    </code>
