Descriptions

The sigalgs implementation in t1_lib.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by using an invalid signature_algorithms extension in the ClientHello message during a renegotiation.

La implementación sigalgs en t1_lib.c en OpenSSL 1.0.2 anterior a 1.0.2a permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída del demonio) mediante el uso de una extensión signature_algorithms inválida en el mensaje ClientHello durante una renegociación.
