Re: [Openvpn-devel] [PATCH v7-master] Add Windows DNS Leak fix using WFP ('block-outside-dns')

[James Yonan]

These may have been fixed by now, but noticed some issues in the 
original patch that was discussed in the OpenVPN-devel IRC meeting 
several weeks ago.

* win_adapter_index_to_luid is declared to return a
  NET_LUID but not all code paths return a value.
* wcscat(svchostpath, L"\\svchost.exe") isn't checking
  for buffer overflow.

* FwpmGetAppIdFromFileName0 must be paired with a
  corresponding FwpmFreeMemory0
