OpenSSL 0.9.8c-1 - 0.9.8g-9 / Debian OpenSSH |
Description |
|
|
Se ha descubierto una vulnerabilidad en OpenSSL 0.9.8c-1 hasta la versión 0.9.8g-9 en Debian. La vulnerabilidad reside en un error de diseño al utilizar un generador de números aleatorios que genera números predecibles. Un atacante remoto podría obtener claves criptográficas (SSH, OpenVPN, DNSSEC, X.509 y SSL/TLS) mediante un ataque de fuerza bruta. Existe un exploit público disponible. |
