Corruption and crashes when using IP options

[thrimbor]

When handling pcap files which contain IP packets with options, libtins either crashes (observed when using EOL or NOP) or corrupts the packet. In the minimal example provided here, libtins overwrites the first byte of the contained UDP-header with a zero, changing the port-number.

I observed this behavior on Arch Linux with libtins 4.0. Version 3.4 on Ubuntu 17.10 seems to be fine instead.

Ugh this sucks, sorry. I know what the issue is, I'll fix it tomorrow and I'll run this with randomized inputs to make sure it doesn't blow up. Thanks for the report!

Just pushed a fix to develop. I'll merge it to master in about an hour.

[thrimbor]

That was quick, thanks!

Could we get a new release including this fix?

[mfontanini]

That's probably a good idea, I'll try to release this tonight.

Just pushed the new tag
