Descriptions

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 42.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Múltiples vulnerabilidades no especificadas en el motor de navegación en Mozilla Firefox en versiones anteriores a 42.0 permiten a atacantes remotos provocar una denegación de servicio (corrupción de memoria y caída de la aplicación) o posiblemente ejecutar código arbitrario a través de vectores desconocidos.

Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky, Randell Jesup, Olli Pettay, Karl Tomlinson, Jeff Walden, Gary Kwong, Andrew McCreight, Georg Fritzsche, and Carsten Book 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.
