Summary
The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.
Security Fix(es):
* gnutls: timing side-channel in the RSA-PSK authentication (CVE-2023-5981)
* gnutls: incomplete fix for CVE-2023-5981 (CVE-2024-0553)
* gnutls: rejects certificate chain with distributed trust (CVE-2024-0567)

Gnutls: incomplete fix for cve-2023-5981
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-chann…

Gnutls: rejects certificate chain with distributed trust
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote cli…
