IBM WebSphere MQ 6.x before 6.0.2.10 and 7.x before 7.0.1.3 allows remote attackers to spoof X.509 certificate authentication, and send or receive channel messages, via a crafted Subject Distinguished Name (DN) value in a certificate.

Unspecified vulnerability in the channel process in IBM WebSphere MQ 7.0 before 7.0.1.2 allows remote authenticated users to cause a denial of service (daemon crash) via "incorrect channel control data."

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.

Unspecified vulnerability in the rriDecompress function in IBM WebSphere MQ 7.0.0.0, 7.0.0.1, and 7.0.0.2 allows remote attackers to cause a denial of service via unknown vectors.

The server in IBM WebSphere MQ 7.0.0.1, 7.0.0.2, and 7.0.1.0 allows attackers to cause a denial of service (trap) or possibly have unspecified other impact via malformed data.

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.

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.

MQSeries 5.1 in IBM WebSphere MQ 5.1 through 5.3.1 on the HP NonStop and Tandem NSK platforms does not require mqm group membership for execution of administrative tasks, which allows local users to bypass intended access restrictions via the runmqsc program, related to "Pathway panels."

The WebSphere MQ XA 5.3 before FP13 and 6.0.x before 6.0.2.1 client for Windows, when running in an MTS or a COM+ environment, grants the PROCESS_DUP_HANDLE privilege to the Everyone group upon connection to a queue manager, which allows local users to duplicate an arbitrary handle and possibly hijack an arbitrary process.

Unspecified vulnerability in IBM WebSphere MQ 6.0.x before 6.0.2.2 and 5.3 before Fix Pack 14 allows attackers to bypass access restrictions for a queue manager via a SVRCONN (MQ client) channel.
