Every time I try to open the attached file in a recent windows build of
Wireshark, when the LDAP dissector is enabled, Wireshark crashes.
If I open the file on my Linux box(Gentoo, WireShark 0.99.5), I am able to read
the file without issue with the dissector enabled.
I have verified this crash on three windows machines, and with WireShark
0.99.4, 0.99.5, and 0.99.6-SVN-21889 - all the windows automated builds.
This packet was modified (MAC,IP,LDAP data - all changed) from a packet
actually captured on the wire, and I was unable to read it with Wireshark on
Windows. I am concerned that this could potentially be an exploitable defect.
