The PMTU discovery procedure used by HP-UX 10.30 and 11.00 for determining the optimum MTU generates large amounts of traffic in response to small packets, allowing remote attackers to cause the system to be used as a packet amplifier.

Security readout for executives and security teams

HP-UX 10.30 and 11.00 can respond to small network packets with disproportionately large traffic during PMTU discovery. An attacker could abuse an exposed system as a traffic amplifier, creating disruption for others and potentially consuming local network capacity. Likely limited to legacy HP-UX 10.30 and 11.00 systems with network paths reachable by untrusted traffic. The bundle does not identify other affected products or versions. Prioritize if legacy HP-UX systems remain exposed to untrusted networks. If none exist, business urgency is low. Because fix details are not in the bundle, remediation should start with asset confirmation and vendor advisory review. Mitigation focus: Identify any HP-UX 10.30 or 11.00 systems still operating.; Review HP advisory HPSBUX0001-110 for vendor-approved fixes or configuration guidance.; Restrict untrusted network access to legacy HP-UX hosts where possible..
