In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the LWAPP dissector could crash. This was addressed in epan/dissectors/packet-lwapp.c by limiting the encapsulation levels to restrict the recursion depth.
In Wireshark 2.4.0 to 2.4.5, the CQL dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-cql.c by checking for a nonzero number of columns.
In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the MP4 dissector could crash. This was addressed in epan/dissectors/file-mp4.c by restricting the box recursion depth.
