epan/dissectors/packet-ncp2222.inc in the NDS dissector in Wireshark 1.12.x before 1.12.13 does not properly maintain a ptvc data structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted packet.

epan/dissectors/packet-mmse.c in the MMSE dissector in Wireshark 1.12.x before 1.12.13 allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

epan/dissectors/packet-ldss.c in the LDSS dissector in Wireshark 1.12.x before 1.12.13 and 2.x before 2.0.5 mishandles conversations, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

epan/dissectors/packet-packetbb.c in the PacketBB dissector in Wireshark 1.12.x before 1.12.13 and 2.x before 2.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted packet.

epan/dissectors/packet-wsp.c in the WSP dissector in Wireshark 1.12.x before 1.12.13 and 2.x before 2.0.5 allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

epan/dissectors/packet-rlc.c in the RLC dissector in Wireshark 1.12.x before 1.12.13 and 2.x before 2.0.5 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (large loop) via a crafted packet.

epan/dissectors/packet-pktc.c in the PKTC dissector in Wireshark 1.12.x before 1.12.11 and 2.0.x before 2.0.3 does not verify BER identifiers, which allows remote attackers to cause a denial of service (out-of-bounds write and application crash) via a crafted packet.

The IEEE 802.11 dissector in Wireshark 1.12.x before 1.12.11 and 2.0.x before 2.0.3 does not properly restrict element lists, which allows remote attackers to cause a denial of service (deep recursion and application crash) via a crafted packet, related to epan/dissectors/packet-capwap.c and epan/dissectors/packet-ieee80211.c.

epan/dissectors/packet-iax2.c in the IAX2 dissector in Wireshark 1.12.x before 1.12.11 and 2.0.x before 2.0.3 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

epan/proto.c in Wireshark 1.12.x before 1.12.11 and 2.0.x before 2.0.3 does not limit the protocol-tree depth, which allows remote attackers to cause a denial of service (stack memory consumption and application crash) via a crafted packet.
