The Chrome Object Wrapper (COW) implementation in Mozilla Firefox
before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before
17.0.6, and Thunderbird ESR 17.x before 17.0.6 does not prevent
acquisition of chrome privileges during calls to content level
constructors, which allows remote attackers to bypass certain
read-only restrictions and conduct cross-site scripting (XSS) attacks
via a crafted web site.
