Descriptions

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 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 navegador en Mozilla Firefox en versiones anteriores a 45.0 y Firefox ESR 38.x en versiones anteriores a 38.7 permite a atacantes remotos causar una denegación de servicio (corrupción de la memoria o caída de la aplicación) o posiblemente ejecutar código arbitrario a través de vectores no especificados.

Francis Gabriel discovered a buffer overflow during ASN.1 decoding in NSS. If a user were tricked in to opening a specially crafted website, 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 Firefox. Bob Clary, Christoph Diehl, Christian Holler, Andrew McCreight, Daniel Holbert, Jesse Ruderman, Randell Jesup, Carsten Book, Gian-Carlo Pascutto, Tyson Smith, Andrea Marchesini, and Jukka Jylanki 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.
