Descriptions

Integer overflow in the PL_ARENA_ALLOCATE implementation in Netscape Portable Runtime (NSPR) in Mozilla Network Security Services (NSS) before 3.19.2.1 and 3.20.x before 3.20.1, as used in Firefox before 42.0 and Firefox ESR 38.x before 38.4 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors.

Desbordamiento de entero en la implementación de PL_ARENA_ALLOCATE en Netscape Portable Runtime (NSPR) en Mozilla Network Security Services (NSS) en versiones anteriores a 3.19.2.1 y 3.20.x en versiones anteriores a 3.20.1, como se utiliza en Firefox en versiones anteriores a 42.0 y Firefox ESR 38.x en versiones anteriores a 38.4 y otros productos, permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria y caída de la aplicación) a través de vectores no especificados.

A heap-based buffer overflow was found in NSPR. An attacker could use this flaw to cause NSPR to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSPR library.
