A vulnerability has been found and corrected in expat:
  The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1,
  as used in the XML-Twig module for Perl, allows context-dependent
  attackers to cause a denial of service (application crash) via an
  XML document with malformed UTF-8 sequences that trigger a buffer
  over-read, related to the doProlog function in lib/xmlparse.c,
  a different vulnerability than CVE-2009-2625 and CVE-2009-3720
  (CVE-2009-3560).
  Packages for 2008.0 are being provided due to extended support for
  Corporate products.
This update provides a solution to these vulnerabilities.
