NVD Description

Note: Versions mentioned in the description apply only to the upstream osbuild-composer package and not the osbuild-composer package as distributed by AlmaLinux. See How to fix? for AlmaLinux:10 relevant fixed versions and status.

Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. 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.
