Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2016-7957)

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.


2) Input validation error (CVE-ID: CVE-2016-7958)

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

In Wireshark 2.2.0, the NCP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/CMakeLists.txt by registering this dissector.
