SUSE SLES15 Security Update : gnutls (SUSE-SU-2024:0638-2)

high Nessus Plugin ID 196939



The remote SUSE host is missing one or more security updates.


The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:0638-2 advisory.

- 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. (CVE-2024-0553)

- 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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
