CVE-2024-0553Source published Source updated
This bulletin covers 2 CVEs. The products, versions, score and guidance below describe the bulletin; check its source for applicability to this specific CVE.
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. The identified vulnerability in the GnuTLS library, designated as CVE-2024-0553, presents a moderate severity concern due to its potential for facilitating timing side-channel attacks in RSA-PSK ciphersuites. While the flaw allows for the exploitation of timing differentials during the key exchange process, enabling attackers to infer sensitive data, its impact is…
