In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the PVFS dissector could crash. This was addressed in epan/dissectors/packet-pvfs2.c by preventing a NULL pointer dereference.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
