## Description

html/parser/XSSAuditor.cpp in WebCore in WebKit, as used in Google Chrome
through 22 and Safari 5.1.7, does not consider all possible output contexts
of reflected data, which makes it easier for remote attackers to bypass a
cross-site scripting (XSS) protection mechanism via a crafted string, aka
rdar problem 12019108.
