Descriptions

The sec_asn1d_parse_leaf function 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, improperly restricts access to an unspecified data structure, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OCTET STRING data, related to a "use-after-poison" issue.

La función sec_asn1d_parse_leaf 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, restringe el acceso de manera incorrecta a una estructura de datos no especificada, lo que permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) o posiblemente ejecutar código arbitrario a través de datos OCTET STRING manipulados, relacionado con un problema 'use-after-poison'.

A use-after-poison flaw was found in the way NSS parsed certain ASN.1 structures. An attacker could use this flaw to cause NSS to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSS library.
