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 client or attacker to
initiate a denial of service attack. (CVE-2024-0567)
A vulnerability was found in GnuTLS. The response times to malformed
ciphertexts in RSA-PSK ClientKeyExchange differ from 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. (CVE-2024-0553)");
