NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/frr-rhel9 package and not the openshift4/frr-rhel9 package as distributed by RHEL.

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.
