Heap-based buffer overflow in IBM WebSphere MQ 6.0 before 6.0.2.11 and 7.0 before 7.0.1.5 allows remote authenticated users to execute arbitrary code or cause a denial of service (queue manager crash) by inserting an invalid message into the queue.
IBM WebSphere MQ 6.0 before 6.0.2.11 and 7.0 before 7.0.1.5 does not use the CRL Distribution Points (CDP) certificate extension, which might allow man-in-the-middle attackers to spoof an SSL partner via a revoked certificate for a (1) client, (2) queue manager, or (3) application.
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.
