The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream webkitgtk package and not the webkitgtk package as distributed by Ubuntu.
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.
