CVE-2018-11356 wireshark: DNS dissector crash in packet-dns.c
A flaw was found in Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the DNS dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. This was addressed in epan/dissectors/packet-dns.c by avoiding a NULL pointer dereference for an empty name in an SRV record.
