NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygems-devel package and not the rubygems-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

RubyGems versions between 2.0.0 and 2.6.13 are vulnerable to a possible remote code execution vulnerability. YAML deserialization of gem specifications can bypass class white lists. Specially crafted serialized objects can possibly be used to escalate to remote code execution.
