gnutls is vulnerable to Information Exposure. The vulnerability is due to differential response times to malformed ciphertexts versus correctly padded PKCS#1 v1.5 ciphertexts during RSA-PSK ClientKeyExchange. This behavior allows an remote attacker to perform a timing side-channel attack, potentially leading to the leakage of sensitive data.
