The dissect_capwap_data function in epan/dissectors/packet-capwap.c in the CAPWAP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 incorrectly uses a -1 data value to represent an error condition, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The dissect_pft function in epan/dissectors/packet-dcp-etsi.c in the DCP ETSI dissector in Wireshark 1.6.x before 1.6.16, 1.8.x before 1.8.8, and 1.10.0 does not validate a certain fragment length value, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The http_payload_subdissector function in epan/dissectors/packet-http.c in the HTTP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 does not properly determine when to use a recursive approach, which allows remote attackers to cause a denial of service (stack consumption) via a crafted packet.
