The checkCss function in includes/Sanitizer.php in the wikitext parser in
MediaWiki before 1.16.3 does not properly validate Cascading Style Sheets
(CSS) token sequences, which allows remote attackers to conduct cross-site
scripting (XSS) attacks or obtain sensitive information by using the \2f\2a
and \2a\2f hex strings to surround CSS comments.
