IBM MQ for HPE NonStop 8.1.0 through 8.1.0.40 IBM MQ C client could allow a remote attacker to cause a denial of service or potentially execute arbitrary code due to improper validation of queue manager responses when requesting AMS policy data...

CVE-2026-11727

IBM MQ for HPE NonStop 8.1.0 through 8.1.0.40 and IBM MQ 9.1 through 10.0.0.0 (Standard Client) are affected by a heap-based buffer overflow (CWE-122) in the MQ client's MQOPEN reply handler . Improper validation of queue manager responses when requesting AMS policy data allows a rogue queue mana...

CVE-2026-69184

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsnameparse enforces backward DNS compression pointers but does not bound the total pointer hops or assembled name length. A malicious DNS server can send a response containing a long descending pointer chain and many resource...

CVE-2026-69186

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsparse trusts the attacker-controlled ANCOUNT, NSCOUNT, and ARCOUNT fields before confirming that the DNS response contains enough bytes for the claimed records. Because processanswer invokes parsing before transaction ID and...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the aresdnsnameparse function due to a lack of limits on the total pointer hops or assembled name length when processing DNS compression pointers. An attacker can cause excessive C...
