squid -- denial of service with forged WCCP messages
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
