Vulnerability details
The vulnerability allows a remote authenticated attacker to cause DoS condition on the target system.
The weakness exists due to insufficient validation of user-supplied input. A remote attacker with authority to connect to a remote queue manager can send a malicious request, cause undefined behaviour within the channel process servicing that connection, including a loss of service for other connections being serviced by the same channel process.
Successful exploitation of the vulnerability may result in denial of service.
