Summary
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. The issue is marked as moderate because it involves a vulnerability in GnuTLS, specifically affecting Cockpit, which utilizes GnuTLS.
This is a bug in the GnuTLS library, Cockpit does not copy this code, but uses the shared lib at runtime. Hence, patching gnutls is necessary and sufficient to address this, hance Cockpit is not affected by this issue.
