Descriptions

crypto/rsa/rsa_ameth.c in OpenSSL 1.0.1 before 1.0.1q and 1.0.2 before 1.0.2e allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an RSA PSS ASN.1 signature that lacks a mask generation function parameter.

crypto/rsa/rsa_ameth.c en OpenSSL 1.0.1 en versiones anteriores a 1.0.1q y 1.0.2 en versiones anteriores a 1.0.2e permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída de aplicación) a través de una firma RSA PSS ASN.1 que carece de un parámetro de función de generación de máscara.

A NULL pointer dereference flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacker could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication.
