SUSE CVE-2023-0361

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...

CVE-2023-0361

CVE-2023-0361 describes a timing side-channel in GnuTLS during RSA ClientKeyExchange handling that can enable Bleichenbacher-style attacks to recover the RSA key and decrypt accompanying application data. The vulnerability affects GnuTLS implementations across multiple advisories and distribution...
