CVE-2017-9344
In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the Bluetooth L2CAP dissector could divide by zero.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.72%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
