+Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
+Date: 2010-12-09
+Initial Package Version: 2.0.1
+Upstream Status: From Upstream
+Origin: Unknown
+Description: Fixes for CVE-2009-2625 (infinite loop and application hang via
+malformed XML) CVE-2009-3560 (DOS via buffer overrun caused by malformed UTF-8)
+and CVE-2009-3720 (DOS via buffer overrun caused by crafted UTF-8). This
+replaces version -2 which had both the original and the revised fixes for
+CVE-2009-3560 - the revised version is supposed to replace the original, not
+add to it, because of problems with certain perl users of libexpat.
