Description Stefan Behte (RETIRED) gentoo-dev Security 2010-02-06 14:49:00 UTC
CVE-2009-3560 (
  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.
