On Windows, fstat() and stat() sets st_dev to different value depending
on whether it was called with file handle or file path. If file handle
was used, the st_dev is simply the file handle casted to unsigned.
If file path was used, then st_dev corresponds to drive letter
(A=0, B=1, C=2, ...).
Compare the files using the file index information retrieved by
GetFileInformationByHandle(). When compiled in configuration that
supports FILE_ID_INFO, the code first tries to obtain 128-bit FILE_ID_INFO
and if that fails, fallback to GetFileInformationByHandle().

Handling security fixes in source package wireshark
Wireshark is a network protocol analyzer and it's ability to perform deep
packet inspection in live traffic may encourage users to use Wireshark/Tshark
as a part of an intrusion detection or traffic monitoring system.
In that case, please note that Wireshark/Tshark may contain remotely
triggerable bugs causing crashes or allowing code injection.
Bugs allowing code injection will be fixed in regular Debian Security
Advisories, but fixes for pure crash bugs may be delayed.
