Red Hat Bugzilla – Bug 463243
Last modified: 2010-03-22 15:35:29 EDT
From MFSA 2008-43:
Security researcher Gareth Heyes reported an issue with the HTML parser in

HTML-escaped. This issue could potentially be used to bypass naive script
filtering and used in an XSS attack. This issue only affected Firefox 2.
