The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The dissect_CPMSetBindings function in epan/dissectors/packet-mswsp.c in the MS-WSP dissector in Wireshark 2.0.x before 2.0.1 does not validate the column size, which allows remote attackers to cause a denial of service (memory consumption or application crash) via a crafted packet.
