In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the AllJoyn dissector could crash with a buffer over-read, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-alljoyn.c by ensuring that a length variable properly tracked the state of a signature variable.
In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the DCERPC dissector could crash with a use-after-free, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-dcerpc-nt.c and epan/dissectors/packet-dcerpc-spoolss.c by using the wmem file scope for private strings.
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.
Stack-based buffer overflow in epan/dissectors/packet-catapult-dct2000.c in the Catapult DCT2000 dissector in Wireshark 2.x before 2.0.6 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 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.
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-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-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-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/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.
