Vulnerability tcp/ip Affected MAC OS up to 8.x Description Spikeman found following. You can kill all the bandwidth out of MacOS up to 8.*, by finding a open port ( only 1 ) and by using synk command line: synk 0 ip open_port then_the_next_port MacOS tcp/ip stack can't handle synfloods and inturn it takes all bandwidth alway from that box.... keep it for 5 mins or so and all conn's from the box _should_ die ( telnets/ftps/ircs/etc )...
