CVE-2013-4936: Null Pointer Dereference

The IsDFP_Frame function in plugins/profinet/packet-pn-rt.c in the PROFINET Real-Time dissector in Wireshark 1.10.x before 1.10.1 does not validate MAC addresses, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted packet.
