Hi,
I was fuzz-testing Wireshark (using fuzz-test.sh) with a dissector I've been
working on, and one of the passes crashed in the generated portion of the LDAP
dissector.
I've extracted the problematic packet into a .pcap file which is attached.
I was able to reproduce the crash in version 1.0.5 as well as my SVN build -
both versions crash every time the capture is loaded. Both tshark and wireshark
exhibit the behaviour.
Please tell me if any other info is required.
Regards
Chris
