CVE-2014-1563

Vulnerabilidad de uso después de liberación en la función mozilla::DOMSVGLength::GetTearOff en Mozilla Firefox anterior a 32.0, Firefox ESR 31.x anterior a 31.1 y Thunderbird 31.x anterior a 31.1 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de la memoria dinámica) a través de una animación SVG con interacción DOM que provoca la recolección incorrecta de ciclos.

Jan de Mooij, Christian Holler, Karl Tomlinson, Randell Jesup, Gary Kwong, Jesse Ruderman and JW Wang discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Abhishek Arya discovered a use-after-free during DOM interactions with SVG. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.
