NVD Description

Note: Versions mentioned in the description apply only to the upstream expat package and not the expat package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

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.
