Symantec Enterprise Firewall may lose large alerts via SNMP

CVE-2002-0302 · published 24 years ago
Summary

The Notify service in Symantec Enterprise Firewall version 6.5 can drop big alert messages when they are sent using SNMP, a network monitoring protocol. This means some security warnings might not reach administrators during an attack. To reduce risk, keep alerts small, consider using a different transport method, and apply any available updates from Symantec that address the behavior.
