Vulnerability Name:

CVE-2023-0361 (CCN-247680)

Assigned:2023-01-20
Published:2023-01-20
Updated:2023-07-25
Summary:GnuTLS could allow a remote attacker to obtain sensitive information, caused by a timing side-channel flaw in the handling of RSA ClientKeyExchange messages. By recovering the secret from the ClientKeyExchange message, an attacker could exploit this vulnerability to decrypt the application data exchanged over that connection, and use this information to launch further attacks against the affected system.
