WatchGuard Information for VU#222750

TCP/IP implementations do not adequately validate ICMP error messages

Status

Affected

Vendor Statement

All WatchGuard firewalls are impacted to some extent by Gont's findings. TCP sessions which terminate on or pass through the firewall are vulnerable to reset attacks when the attacker can guess the source and destination address and port combinations for that session. WatchGuard plans to address the issues raised by Gont's paper for all products in software releases currently scheduled for the Q2-Q3 2005 time frame. If you have further questions about this or any other security concern with WatchGuard products, please contact:
