What is CVE-2024-0553?

A vulnerability exists in GnuTLS where the response times to malformed ciphertexts during RSA-PSK ClientKeyExchange differ significantly from responses to correctly padded ciphertexts. This discrepancy can be exploited by remote attackers to execute timing side-channel attacks, which may lead to the unintended leakage of sensitive data. It is important to note that this vulnerability is classified as an incomplete resolution for a previously identified issue and necessitates prompt attention to secure data transmissions effectively.
