Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
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.
