Descriptions
The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client.
La función ssl_get_algorithm2 en ssl/s3_lib.c en OpenSSL anterior a v1.0.2 obtiene un cierto número de versión de una estructura de datos incorrectos, lo que permite a atacantes remotos provocar una denegación de servicio (caída del demonio) a través de tráfico de red de un cliente TLS v1.2.
