Descriptions

A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade any TLS connections to a vulnerable server.

Se ha detectado un ataque de oráculo de relleno basado en canales laterales de tipo Bleichenbacher en la manera en la que gnutls maneja la verificación de los datos PKCS#1 v1.5 descifrados de un cifrado RSA. Un atacante que sea capaz de ejecutar un proceso en el mismo núcleo físico que el proceso víctima podría usarlo para extraer texto plano o, en algunos casos, desactualizar algunas conexiones TLS a un servidor vulnerable.
