Eli Biham and Lior Neumann discovered a cryptographic weakness in the Bluetooth LE SC pairing protocol, called the Fixed Coordinate Invalid Curve Attack (CVE-2018-5383). Depending on the devices used, this could be exploited by a nearby attacker to obtain sensitive information, for denial of service, or for other security impact.
This flaw has been fixed in firmware for Intel Wireless 7260 (B3), 7260 (B5), 7265 (D1), and 8264 adapters, and for Qualcomm Atheros QCA61x4 “ROME” version 3.2 adapters. Other Bluetooth adapters are also affected and remain vulnerable.
For Debian 7 Wheezy, these problems have been fixed in version 20161130-5~deb7u1.
We recommend that you upgrade your firmware-nonfree packages.
