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 MMSE dissector could go into an infinite loop. This was addressed in epan/proto.c by adding offset and length validation.
CVE-2018-14340
PUBLISHED: 2018-07-19
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-2018-14341

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-2018-14342
PUBLISHED: 2018-07-19
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 BGP protocol dissector could go into a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.
