Description
The Web Workers implementation in Mozilla Firefox before 23.0, Firefox ESR 17.x before 17.0.8, Thunderbird before 17.0.8, Thunderbird ESR 17.x before 17.0.8, and SeaMonkey before 2.20 does not properly restrict XMLHttpRequest calls, which allows remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via unspecified vectors.
