VULHUB ™

The implementation of bridging in OpenBSD is reportedly susceptible to a denial of service vulnerability. This vulnerability presents itself when an OpenBSD host is configured to bridge two or more networks. Additionally, the 'link2' flag must be set on the bridging device. This flag is designed to transparently join multiple networks via an IPSec VPN tunnel. This vulnerability may allow an attacker to crash or reboot affected computers, denying service to legitimate users. A fix was applied in CVS to OpenBSD-current on 18 Aug 2004.
