CVE-2018-5336
In Wireshark 2.4.0 to 2.4.3 and 2.2.0 to 2.2.11, the JSON, XML, NTP, XMPP, and GDB dissectors could crash.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.74%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
