WatchGuard SOHO Firewall Malformed TCP Packet DoS Vulnerability

WatchGuard SOHO Firewall Malformed TCP Packet DoS Vulnerability

WatchGuard SOHO Firewall is a firewall appliance intended for use by Home Office/Small Office users. It offers built-in VPN capabilities.

WatchGuard SOHO Firewall crashes when handling certain types of malformed TCP packets. Upon attempting to forward a packet with bad IP options, the firewall will crash and reboot. All current connections will drop when this occurs.

It should be noted that this is only an issue for packets that are forwarded by the firewall appliance.
