The dissect_rohc_ir_packet function in epan/dissectors/packet-rohc.c in the ROHC dissector in Wireshark 1.8.x before 1.8.5 does not properly handle unknown profiles, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

The rtps_util_add_bitmap function in epan/dissectors/packet-rtps.c in the RTPS dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly implement certain nested loops for processing bitmap data, which allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.

The dissect_pw_eth_heuristic function in epan/dissectors/packet-pw-eth.c in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly handle apparent Ethernet address values at the beginning of MPLS data, which allows remote attackers to cause a denial of service (loop) via a malformed packet.

The dissect_r3_cmd_alarmconfigure function in epan/dissectors/packet-assa_r3.c in the R3 dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly handle a certain alarm length, which allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.

Multiple buffer overflows in the dissect_pft_fec_detailed function in the DCP-ETSI dissector in epan/dissectors/packet-dcp-etsi.c in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 allow remote attackers to cause a denial of service (application crash) via a malformed packet.

epan/tvbuff.c in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly validate certain length values for the MS-MMC dissector, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

The csnStreamDissector function in epan/dissectors/packet-csn1.c in the CSN.1 dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly handle a large number of padding bits, which allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.

The dissect_version_4_primary_header function in epan/dissectors/packet-dtn.c in the DTN dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 accesses an inappropriate pointer, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

The dissect_version_5_and_6_primary_header function in epan/dissectors/packet-dtn.c in the DTN dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 accesses an inappropriate pointer, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

Double free vulnerability in epan/proto.c in the dissection engine in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 allows remote attackers to cause a denial of service (application crash) via a malformed packet.
