QID 378553: IBM MQ Blockchain bridge Denial of Service (DoS) Vulnerability within protobuf-java core (6853381)

IBM MQ is a message oriented middleware that allows independent and non-concurrent applications on a distributed system to communicate with each other.

Affected Version:
IBM MQ 9.2, 9.3

QID Detection Logic: (Authenticated)
Operating System: Linux
The QID runs the command "/opt/mqm/bin/dspmqver -v | grep -A3 '^Name' to see if the system is running a vulnerable version of IBM MQ or not.

By sending non-repeated embedded messages with repeated or unknown fields, a remote authenticated attacker could exploit this vulnerability to cause long garbage collection pauses.
