Descriptions

The ssl3_client_hello function in s3_clnt.c in OpenSSL 1.0.2 before 1.0.2a does not ensure that the PRNG is seeded before proceeding with a handshake, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by sniffing the network and then conducting a brute-force attack.

La función ssl3_client_hello en s3_clnt.c en OpenSSL 1.0.2 anterior a 1.0.2a no asegura que el PRNG está sembrado antes de proceder con una negociación, lo que facilita a atacantes remotos superar los mecanismos de protección criptográficos mediante la captura de trafico de la red y posteriormente realizar un ataque de fuerza bruta.
