Descriptions

Race condition in the GetStaticInstance function in the WebRTC implementation in Mozilla Firefox before 45.0 might allow remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via unspecified vectors.

Condición de carrera en la función GetStaticInstance en la implementación de WebRTC en Mozilla Firefox en versiones anteriores a 45.0 podría permitir a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (uso después de liberación de memoria) 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.
