In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the VLAN dissector could crash. This was addressed in epan/dissectors/packet-vlan.c by limiting VLAN tag nesting to restrict the recursion depth.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the NBAP dissector could crash with a large loop that ends with a heap-based buffer overflow. This was addressed in epan/dissectors/packet-nbap.c by prohibiting the self-linking of DCH-IDs.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the IEEE 802.15.4 dissector could crash. This was addressed in epan/dissectors/packet-ieee802154.c by ensuring that an allocation step occurs.

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.

In Wireshark 2.4.0 to 2.4.5, the TCP dissector could crash. This was addressed in epan/dissectors/packet-tcp.c by preserving valid data sources.

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 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 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the DMP dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-dmp.c by correctly supporting a bounded number of Security Categories for a...

In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the pcapng file parser could crash. This was addressed in wiretap/pcapng.c by adding a block-size check for sysdig event blocks.

In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the NBAP dissector could crash. This was addressed in epan/dissectors/asn1/nbap/nbap.cnf by ensuring DCH ID initialization.
