NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift-clients-redistributable package and not the openshift-clients-redistributable package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification.
