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 RHEL.

When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly applied, and only the last constraint will be considered.
