Packets of Death


very nice detective work, in which we discover that a single ill-favored packet can completely kill certain Intel gigabit NICs (to the point that a power cycle is required to resurrect them). Excellent writeup (and I discovered a new tool: open source packet generation suite Ostinato, which aims to be “wireshark in reverse”).

The significance, via Slashdot: “With a modified HTTP server configured to generate the data at byte value (based on headers, host, etc) you could easily configure an HTTP 200 response to contain the packet of death and kill client machines behind firewalls!”
