epan/dissectors/packet-ipmi-trace.c in the IPMI trace dissector in Wireshark 2.x before 2.0.6 does not properly consider whether a string is constant, which allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted packet.

epan/dissectors/packet-qnet6.c in the QNX6 QNET dissector in Wireshark 2.x before 2.0.6 mishandles MAC address data, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet.

epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap and application crash) via a crafted packet.

epan/dissectors/packet-catapult-dct2000.c in the Catapult DCT2000 dissector in Wireshark 2.x before 2.0.6 does not restrict the number of channels, which allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted packet.

epan/dissectors/packet-umts_fp.c in the UMTS FP dissector in Wireshark 2.x before 2.0.6 does not ensure that memory is allocated for certain data structures, which allows remote attackers to cause a denial of service (invalid write access and application crash) via a crafted packet.

The USB subsystem in Wireshark 1.12.x before 1.12.12 and 2.x before 2.0.4 mishandles class types, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

epan/dissectors/packet-umts_fp.c in the UMTS FP dissector in Wireshark 1.12.x before 1.12.12 and 2.x before 2.0.4 mishandles the reserved C/T value, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

wiretap/netscreen.c in the NetScreen file parser in Wireshark 1.12.x before 1.12.12 and 2.x before 2.0.4 mishandles sscanf unsigned-integer processing, which allows remote attackers to cause a denial of service (application crash) via a crafted file.

epan/dissectors/packet-pktap.c in the Ethernet dissector in Wireshark 2.x before 2.0.4 mishandles the packet-header data type, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

wiretap/cosine.c in the CoSine file parser in Wireshark 1.12.x before 1.12.12 and 2.x before 2.0.4 mishandles sscanf unsigned-integer processing, which allows remote attackers to cause a denial of service (application crash) via a crafted file.
