Technical details
A heap buffer overflow exists in IBM MQ's processing of MQPUT and MQPUT1 operations when message handle properties are malformed. The vulnerability requires authentication to the MQ system and can result in denial of service or remote code execution. While no public exploits are known, the high CVSS score (8.8) and code execution potential make this a significant risk for authenticated attack scenarios.
