The SavedStacks class in the JavaScript implementation in Mozilla Firefox before 41.0, when the Debugger API is enabled, allows remote attackers to cause a denial of service (getSlotRef assertion failure and application exit) or possibly execute arbitrary code via a crafted web site.
Vulnerabilidad en la clase SavedStacks en la implementación JavaScript en Mozilla Firefox en versiones anteriores a 41.0, cuando la API Debugger está habilitada, permite a atacantes remotos provocar una denegación de servicio (fallo de aserción getSlotRef y salida de la aplicación) o posiblemente ejecutar código arbitrario a través de un sitio web manipulado.
USN-2743-1 fixed vulnerabilities in Firefox. After upgrading, some users reported problems with bookmark creation and crashes in some circumstances. This update fixes the problem. Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Bob Clary and Randell Jesup discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, 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 Firefox. Various other issues were also addressed.
