CVE-2011-2997

Múltiples vulnerabilidades no especificadas en el motor del navegador de Mozilla Firefox anteriores a v6, Thunderbird anteriores a v7.0 y SeaMonkey anteriores a v2.4, permiten a atacantes remotos causar una denegación de servicio (corrupción de memoria y caída de la aplicación) o posiblemente ejecutar código arbitrario a través de vectores desconocidos.

Security issues were identified and fixed in Mozilla Firefox and Thunderbird. Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent the starting of a download in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site. Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service or possibly execute arbitrary code via unknown vectors. Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not properly handle HTTP responses that contain multiple Location, Content-Length, or Content-Disposition headers, which makes it easier for remote attackers to conduct HTTP response splitting attacks via crafted header values. Various other issues were also addressed.
