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

Packages for 2008.0 are provided for Corporate Desktop 2008.0
The previous (MDVSA-2009:316-2) updates provided packages for
2008.0/2009.0/2009.1/2010.0/mes5 that did not have an increased
release number which prevented the packages from hitting the mirrors.
