In Wireshark 2.4.0 to 2.4.1 and 2.2.0 to 2.2.9, the BT ATT dissector could crash. This was addressed in epan/dissectors/packet-btatt.c by considering a case where not all of the BTATT packets have the same encapsulation level.
In Wireshark 2.4.0 to 2.4.1 and 2.2.0 to 2.2.9, the MBIM dissector could crash or exhaust system memory. This was addressed in epan/dissectors/packet-mbim.c by changing the memory-allocation approach.
In Wireshark 2.4.0, the Modbus dissector could crash with a NULL pointer dereference. This was addressed in epan/dissectors/packet-mbtcp.c by adding length validation.
In Wireshark 2.4.0, 2.2.0 to 2.2.8, and 2.0.0 to 2.0.14, the IrCOMM dissector has a buffer over-read and application crash. This was addressed in plugins/irda/packet-ircomm.c by adding length validation.
In Wireshark 2.4.0 and 2.2.0 to 2.2.8, the Profinet I/O dissector could crash with an out-of-bounds write. This was addressed in plugins/profinet/packet-dcerpc-pn-io.c by adding string validation.
In Wireshark 2.4.0, 2.2.0 to 2.2.8, and 2.0.0 to 2.0.14, the MSDP dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-msdp.c by adding length validation.
In Wireshark 2.2.0 to 2.2.7 and 2.0.0 to 2.0.13, the DOCSIS dissector could go into an infinite loop. This was addressed in plugins/docsis/packet-docsis.c by rejecting invalid Frame Control parameter values.
In Wireshark 2.2.0 to 2.2.7 and 2.0.0 to 2.0.13, the MQ dissector could crash. This was addressed in epan/dissectors/packet-mq.c by validating the fragment length before a reassembly attempt.
In Wireshark 2.2.0 to 2.2.7 and 2.0.0 to 2.0.13, the AMQP dissector could crash. This was addressed in epan/dissectors/packet-amqp.c by checking for successful list dissection.
In Wireshark 2.0.0 to 2.0.13, the GPRS LLC dissector could go into a large loop. This was addressed in epan/dissectors/packet-gprs-llc.c by using a different integer data type.
