NVD Description

Note: Versions mentioned in the description apply only to the upstream go-toolset:rhel8/golang-misc package and not the go-toolset:rhel8/golang-misc package as distributed by RHEL. See How to fix? for RHEL:8 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.
