Descriptions
Mozilla Firefox before 3.6 Beta 3 does not properly handle overlong UTF-8 encoding, which makes it easier for remote attackers to bypass cross-site scripting (XSS) protection mechanisms via a crafted string, a different vulnerability than CVE-2010-1210.
Mozilla Firefox anterior v3.6 Beta 3 no maneja adecuadamente codificaciones UTF-8 demasiado largas, lo que hace facil para atacantes remotos superar los mecanísmos de protección de secuencias de comandos en sitios cruzados (XSS) a través de cadenas manipuladas, una vulnerabilidad diferente que CVE-2010-1210.
