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_oampdu_event_notification function in epan/dissectors/packet-slowprotocols.c in the IEEE 802.3 Slow Protocols dissector in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly handle certain short lengths, which allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.

The dissect_rtcp_app function in epan/dissectors/packet-rtcp.c in the RTCP dissector in Wireshark 1.6.x before 1.6.12 and 1.8.x before 1.8.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

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.

Integer overflow in the dissect_iscsi_pdu function in epan/dissectors/packet-iscsi.c in the iSCSI dissector in Wireshark 1.6.x before 1.6.12 and 1.8.x before 1.8.4 allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.

The dissect_isakmp function in epan/dissectors/packet-isakmp.c in the ISAKMP dissector in Wireshark 1.6.x before 1.6.12 and 1.8.x before 1.8.4 uses an incorrect data structure to determine IKEv2 decryption parameters, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.
