epan/dissectors/packet-ncp2222.inc in the NDS dissector in Wireshark 1.12.x before 1.12.13 does not properly maintain a ptvc data structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted packet.
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.
