NVD Description

Note: Versions mentioned in the description apply only to the upstream polaris package and not the polaris package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
