Descriptions

OpenSSL 0.9.8i and earlier does not properly check the return value from the EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys.

OpenSSL 0.9.8i y versiones anteriores no comprueba correctamente el valor de retorno de la función EVP_VerifyFinal, lo que permite a atacantes remotos evitar la validación de la cadena del certificado a través de una firma SSL/TLS mal formada para las claves DSA y ECDSA.
