Synopsis

A message queuing service installed on the remote host is affected by a denial-of-service vulnerability.

Description

According to its self-reported version, the IBM MQ server installed on the remote host is 8.0.0.x prior to 8.0.0.11 LTS, 9.0.0.x prior to 9.0.0.6 LTS, 9.1.0.x prior to 9.1.0.2 LTS, or 9.1.1 CD and is therefore affected by a denial-of-service vulnerability in the IBM MQ Queue Manager due to a weakness in the TLS key renegotiation functions. An unauthenticated, remote attacker could exploit this vulnerability to impact the availability of the service.

Solution

Upgrade to IBM MQ 8.0.0.11, 9.0.0.6, 9.1.0.2, 9.1.2 or later as per the vendor advisory.
