"In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the
Radiotap dissector could crash. This was addressed in
epan/dissectors/packet-ieee80211-radiotap-iter.c by validating
iterator operations. (CVE-2018-16057)

In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the MMSE dissector
could go into an infinite loop. This was addressed in
epan/dissectors/packet-mmse.c by preventing length overflows.
(CVE-2018-19622)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the
Bazaar protocol dissector could go into an infinite loop. This was
addressed in epan/dissectors/packet-bzr.c by properly handling items
that are too long. (CVE-2018-14368 )

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15,
dissectors that support zlib decompression could crash. This was
addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid
a buffer over-read. (CVE-2018-14340)

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the
DICOM dissector could go into a large or infinite loop. This was
addressed in epan/dissectors/packet-dcm.c by preventing an offset
overflow. (CVE-2018-14341)

In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the LDSS
dissector could crash. This was addressed in
epan/dissectors/packet-ldss.c by avoiding a buffer over-read upon
encountering a missing '\0' character. (CVE-2018-11362)

In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the SIGCOMP dissector
could crash. This was addressed in epan/dissectors/packet-sigcomp.c by
correcting the extraction of the length value. (CVE-2018-7418)");
