Mq For Hpe Nonstop
Monthly
Heap-based buffer overflow in the IBM MQ C client shipped with IBM MQ for HPE NonStop 8.1.0 through 8.1.0.40 lets a remote attacker who controls the queue manager's responses crash the client process or potentially execute arbitrary code in its context (CVSS 3.1 base 8.1). The flaw is triggered when the client requests AMS (Advanced Message Security) policy data and the client fails to properly validate the returned queue manager response; exploitation is unauthenticated from the client side (PR:N) but requires the attacker to operate a malicious or compromised queue manager or to man-in-the-middle the client-to-queue-manager channel, which is why the vector carries AC:H. No public exploit code or confirmed active exploitation was identified at time of analysis, and a vendor patch is available.
Improper validation of message header offset values in IBM MQ for HPE NonStop 8.1.0 through 8.1.0.40 allows an authenticated MQ user with network reach to an affected queue manager to trigger an out-of-bounds read, which can leak queue manager memory (high confidentiality impact) and crash the broker (high availability impact), yielding a CVSS 3.1 score of 8.1. Exploitation requires valid credentials - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H - but no user interaction, and the requirement for authentication rules out anonymous abuse while the flaw is confined to the HPE NonStop platform port rather than all MQ deployments. No public exploit identified at time of analysis; a vendor patch is referenced in IBM's advisory.
IBM MQ for HPE NonStop versions 8.1.0 through 8.1.0.40 contain a heap-based buffer overflow (CWE-122) that is triggered during queue manager startup when improperly validated cluster migration data is processed. The flaw is exploitable only by an authenticated attacker who can supply crafted migration data to a queue manager participating in MQ clustering, and the dependable outcome is a denial of service (queue manager startup failure or crash), with arbitrary code execution considered only potentially achievable. Independent assessment rates the realistic impact lower than the vendor's 7.5 score (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:H), and there is confirmed no public exploit code and no CISA KEV listing - no public exploit identified at time of analysis. A vendor patch is available via IBM support page node 7287705.
Heap-based memory corruption in the IBM MQ for HPE NonStop queue manager lets an attacker who already holds a valid, low-privileged authenticated channel connection (PR:L) crash or potentially take over the broker by sending a message carrying a malformed distribution list structure, yielding the full confidentiality, integrity and availability impact reflected in the CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The flaw is a heap buffer overflow (CWE-122) arising from improper validation of the multi-recipient list records embedded in an MQ message, so exploitation is network-reachable and requires no user interaction, but it is not reachable pre-authentication or against a default queue manager configuration. IBM has published a vendor patch and no public exploit code or evidence of active exploitation was identified at time of analysis.
Heap buffer underflow in IBM MQ for HPE NonStop 8.1.0 through 8.1.0.40 allows an authenticated remote attacker to crash or destabilize the queue manager, and potentially to execute arbitrary code, by submitting a crafted multi-segment message that is reassembled during processing. The dependable outcome is denial of service: reliable code execution is not confirmed, and exploitation requires valid low-privilege credentials (PR:L) plus access to a channel or queue that accepts submitted messages. There is no public exploit identified at time of analysis and the flaw has not been added to CISA KEV; urgency is real but constrained because only the specialized HPE NonStop build is affected, not general IBM MQ distributions.
Heap corruption in IBM MQ for HPE NonStop 8.1.0 through 8.1.0.40 allows an authenticated remote user with a valid MQ session to crash the queue manager via a crafted MQINQ inquire request, and the same integer-overflow defect in request validation creates the potential for privilege escalation under specific memory-layout conditions. The issue is rated 7.5 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H), meaning credentials are required and the overflow is non-trivial to trigger reliably; there is no public exploit code and no public exploit identified at time of analysis, and IBM has published a vendor fix. Risk is further bounded because exploitation is confined to the specialized HPE NonStop platform running the affected 8.1.0.x maintenance levels, so deployments that have applied the patched level are not exposed.
