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.
