## Description

A vulnerability was found in GnuTLS. The response times to malformedciphertexts in RSA-PSK ClientKeyExchange differ from the response times ofciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remoteattacker to perform a timing side-channel attack in the RSA-PSK keyexchange, potentially leading to the leakage of sensitive data.CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.
