Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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. This was addressed in epan/dissectors/packet-dns.c by avoiding a NULL pointer dereference for an empty name in an SRV record.
