Summary

In the Linux kernel, the following vulnerability has been resolved:

ipv4: validate checksum_start before completing checksum

If a packet with bad checksum metadata gets into the ipv4 stack, skb_checksum_help can corrupt the network header and cause a bunch of mischief.

This was discovered and reported by Paulos, and has been reporoduced by others independently since.

We really shouldn't allow such packets in, but as a defence in depth measure, let's also check before we complete the checksum.

A more complete validation at input is forthcoming, but needs more work.
