Fixed In Version: gnutls 3.8.3
Doc Type: If docs needed, set a value
Doc Text:
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.

Description TEJ RATHI 2024-01-15 07:29:42 UTC 
While the fix released for CVE-2023-5981 improves the side-channel situation, it does not eliminate the side-channel leakage in RSA-PSK ciphersuites.
