Vulnerability description

DayBreach CVE AI Research

CVE-2024-0553 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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