Description
The dissect_wtp_common function in epan/dissectors/packet-wtp.c in the WTP dissector in Wireshark 1.6.x before 1.6.12 and 1.8.x before 1.8.4 uses an incorrect data type for a certain length field, which allows remote attackers to cause a denial of service (integer overflow and infinite loop) via a crafted value in a packet.
