The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to
5.0.0RC3, does not filter null (\0) characters within tag names when
restricting input to allowed tags, which allows dangerous tags to be
processed by web browsers such as Internet Explorer and Safari, which
ignore null characters and facilitate the exploitation of cross-site
scripting (XSS) vulnerabilities.
