Ubuntu Security Notice 5901-1 - Hubert Kario discovered that GnuTLS had a timing side-channel when handling certain RSA messages. A remote attacker could possibly use this issue to recover sensitive information.

Debian Linux Security Advisory 5349-1 - Hubert Kario discovered a timing side channel in the RSA decryption implementation of the GNU TLS library.

A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection.
