Security Bulletin: IBM WebSphere MQ potential denial of service vulnerability in command server (CVE-2014-4771)
There is a potential for a malicious user to increase the time it takes for the command server to process PCF response messages which could be exploited in such a way to cause a denial of service.
DESCRIPTION: IBM WebSphere MQ could allow a malicious privileged user with access to put PCF inquiries to the command input queue, to craft a query that would create an artificially full reply queue. This would prevent other users from submitting queries to the system.
