Vulnerability details
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in message decompression when processing attacker-supplied compressed message bodies. A remote user can publish a specially crafted compressed message to cause a denial of service.
Only applications that have enabled message decompression are vulnerable. A single poison message may cause the service to crash-loop because it is redelivered after restart.
Affected software
