## Description

Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before
2.12 do not prevent use of the Object.defineProperty method to shadow the
location object (aka window.location), which makes it easier for remote
attackers to conduct cross-site scripting (XSS) attacks via vectors
involving a plugin.
