Descriptions

The HZ-GB-2312 character-set implementation in Mozilla Firefox before 17.0, Firefox ESR 10.x before 10.0.11, Thunderbird before 17.0, Thunderbird ESR 10.x before 10.0.11, and SeaMonkey before 2.14 does not properly handle a ~ (tilde) character in proximity to a chunk delimiter, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document.

La implementación del juego de caracteres HZ-GB-2312 en Mozilla Firefox anterior a v17.0, Firefox ESR v10.x anterior a v10.0.11, Thunderbird anterior a v17.0, Thunderbird ESR v10.x anterior a v10.0.11, y SeaMonkey anterior a v2.14 no maneja correctamente el caracter ~ (tilde) en proximidad con un delimitador, lo que permite a atacantes remotos llevar a cabo un ataque XSS mediante un documento manipulado.
