Unspecified vulnerability in the queue manager in IBM WebSphere MQ (WMQ) 5.3, 6.0 before 6.0.2.6, and 7.0 before 7.0.0.2 allows local users to gain privileges via vectors related to the (1) setmqaut, (2) dmpmqaut, and (3) dspmqaut authorization commands.

IBM WebSphere MQ 6.x through 6.0.2.7, 7.0.0.0, 7.0.0.1, 7.0.0.2, and 7.0.1.0, when read ahead or asynchronous message consumption is enabled, allows attackers to have an unspecified impact via unknown vectors, related to a "memory overwrite" issue.

Buffer overflow in the queue manager in IBM WebSphere MQ 6.x before 6.0.2.7 and 7.x before 7.0.1.0 allows remote attackers to execute arbitrary code via a crafted request.

IBM WebSphere MQ 6.0 before 6.0.2.9 and 7.0 before 7.0.1.1 does not encrypt the username and password in the security parameters field, which allows remote attackers to obtain sensitive information by sniffing the network traffic from a .NET client application.
