NVD Description

Note: Versions mentioned in the description apply only to the upstream jruby package and not the jruby package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 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.
