According to its self-reported version, the IBM MQ server installed on the remote host is 8.0.0.x prior to 8.0.0.15, 8.1.0.x prior to 8.1.0.5 with APAR IT28019, 9.1.0.x prior to 9.1.0.5, or 9.1.x prior to 9.1.5 and is therefore affected by a denial of service vulnerability. An authenticated, remote attacker can exploit this issue and cause a queue processing error crashing the affected host.
