CVE-2016-7957: Wireshark

High severity, CVSS 7.5. EPSS: 1.9% chance of exploitation in the next 30 days.

In Wireshark 2.2.0, the Bluetooth L2CAP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-btl2cap.c by avoiding use of a seven-byte memcmp for potentially shorter strings.
