Impact
Remote, unauthenticated attackers can crash the HPE NonStop SNMP Trap Multiplexer service, causing a denial of service. They only need network access to send malformed SNMP packets to the service.
Root cause
A stack-based buffer overflow (CWE-121) allows memory corruption when parsing SNMP trap inputs.
