Issue in PacketGetStats, buffer overrun

[gvarenni]

PacketGetStats writes
win10pcap.patch.txt

a field in the structure pcap_stats that should NOT be touched, bs_capt. Due to some bad mojo in pcap_stats and pcap_stats_ex on windows (wpcap.dll), pcap_stats uses a 3-fields version of struct pcap_stats, pcap_stats_ex uses a bigger one. PacketGetStatsEx is the function that can write into bs_capt.

This is clearly written in the original sources for packet.dll from the original WinPcap (winpcap.org).

Patch is attached.
