ext/filter in PHP 5.2.0, when FILTER_SANITIZE_STRING is used with the
FILTER_FLAG_STRIP_LOW flag, does not properly strip HTML tags, which allows
remote attackers to conduct cross-site scripting (XSS) attacks via HTML
with a ‘<’ character followed by certain whitespace characters, which
passes one filter but is collapsed into a valid tag, as demonstrated using
%0b.
