IBM WebSphere MQ 8.0.0.0 through 9.1.1 could allow a local user to inject code that could be executed with root privileges. This is due to an incomplete fix for CVE-2018-1792. IBM X-ForceID: 154887.

IBM WebSphere 8.0.0.0 through 9.1.1 could allow an authenticated attacker to escalate their privileges when using multiplexed channels. IBM X-Force ID: 153915.

IBM WebSphere MQ 8.0.0.0 through 8.0.0.10, 9.0.0.0 through 9.0.0.5, 9.0.1 through 9.0.5, and 9.1.0.0 could allow a local user to inject code that could be executed with root privileges. IBM X-Force ID: 148947.

IBM WebSphere MQ 8.0 through 9.1 is vulnerable to a error with MQTT topic string publishing that can cause a denial of service attack. IBM X-Force ID: 145456.

IBM WebSphere MQ 7.5, 8.0, and 9.0 could allow a remotely authenticated attacker to to send invalid or malformed headers that could cause messages to no longer be transmitted via the affected channel. IBM X-Force ID: 141339.

An IBM WebSphere MQ (Maintenance levels 7.1.0.0 - 7.1.0.9, 7.5.0.0 - 7.5.0.8, 8.0.0.0 - 8.0.0.8, 9.0.0.0 - 9.0.0.2, and 9.0.0 - 9.0.4) client connecting to a Queue Manager could cause a SIGSEGV in the Channel process amqrmppa. IBM X-Force ID: 137775.

IBM WebSphere MQ 8.0 and 9.0, when configured to use a PAM module for authentication, could allow a user to cause a deadlock in the IBM MQ PAM code which could result in a denial of service. IBM X-Force ID: 138949.

IBM WebSphere MQ 8.0 through 8.0.0.8 and 9.0 through 9.0.4 under special circumstances could allow an authenticated user to consume all resources due to a memory leak resulting in service loss. IBM X-Force ID: 136975.

IBM WebSphere MQ 7.5.x before 7.5.0.6 and 8.0.x before 8.0.0.3 allows remote authenticated users to obtain sensitive information via a man-in-the-middle attack, related to duplication of message data in cleartext outside the protected payload. IBM X-Force ID: 103482.

IBM WebSphere MQ 7.0, 7.1, 7.5, 8.0, and 9.0 service trace module could be used to execute untrusted code under 'mqm' user. IBM X-Force ID: 132953.

IBM MQ Managed File Transfer Agent 8.0 and 9.0 sets insecure permissions on certain files it creates. A local attacker could exploit this vulnerability to modify or delete data contained in the files with an unknown impact. IBM X-Force ID: 134391.

IBM WebSphere MQ 8.0 and 9.0 could allow an authenticated user with authority to send a specially crafted request that could cause a channel process to cease processing further requests. IBM X-Force ID: 131547.

IBM WebSphere MQ 7.5, 8.0, and 9.0 could allow a local user to crash the queue manager agent thread and expose some sensitive information. IBM X-Force ID: 126454.

IBM WebSphere MQ 7.5, 8.0, and 9.0 could allow an authenticated user to insert messages with a corrupt RFH header into the channel which would cause it to restart. IBM X-Force ID: 127803.

IBM WebSphere MQ 8.0 and 9.0 could allow, under special circumstances, an unauthorized user to access an object which they should have been denied access. IBM X-Force ID: 126456.

IBM WebSphere MQ 8.0 and 9.0 could allow an authenticated user to cause a shared memory leak by MQ applications using dynamic queues, which can lead to lack of resources for other MQ applications. IBM X-Force ID: 125144.

IBM WebSphere MQ 8.0 could allow an authenticated user to cause a premature termination of a client application thread which could potentially cause denial of service. IBM X-Force ID: 123914.
