FreeBSD : squid -- denial of service with forged WCCP messages (5fe7e27a-64cb-11d9-9e1e-c296ac722cb3)
Medium Nessus Plugin ID 18953
The remote FreeBSD host is missing a security-related update.
The squid patches page notes : WCCP_I_SEE_YOU messages contain a 'number of caches' field which should be between 1 and 32. Values outside that range may crash Squid if WCCP is enabled, and if an attacker can spoof UDP packets with the WCCP router's IP address.
