## Affected versions

- IBM MQ: affected >= 9.1.0.0 and <= 9.1.0.37 LTS; >= 9.2.0.0 and <= 9.2.0.43 LTS; >= 9.3.0.0 and <= 9.3.0.41 LTS; >= 9.3.0.0 and <= 9.3.5.1 CD; >= 9.4.0.0 and <= 9.4.0.25 LTS; >= 9.4.0.0 and <= 9.4.5.1 CD; 10.0.0.0

A version outside these ranges is not a statement that it is unaffected.

## Impact

Authenticated attacker can craft malformed MQPUT distribution headers to trigger heap overflow, causing DoS or potential privilege escalation on IBM MQ servers.

## Action

Patch when possible

## Recommendation

Apply IBM's MQ security update immediately; restrict MQ access and monitor MQPUT traffic.
