CVE-2011-4101: Null Pointer Dereference
A flaw in the Infiniband dissector could cause Wireshark 1.4.0 through 1.4.9 and 1.6.0 through 1.6.3 to crash by dereferencing a NULL pointer by reading a malformed packet trace file or if someone were to inject a malformed packet onto the wire. This is corrected in wireshark 1.6.3
