Several vulnerabilities have been discovered in the firmware for
Broadcom BCM43xx wifi chips that may lead to a privilege escalation
or loss of confidentiality.
CVE-2016-0801
Broadgate Team discovered flaws in packet processing in the
Broadcom wifi firmware and proprietary drivers that could lead to
remote code execution. However, this vulnerability is not
believed to affect the drivers used in Debian.
CVE-2017-0561
Gal Beniamini of Project Zero discovered a flaw in the TDLS
implementation in Broadcom wifi firmware. This could be exploited
by an attacker on the same WPA2 network to execute code on the
wifi microcontroller.
CVE-2017-9417 / #869639
Nitay Artenstein of Exodus Intelligence discovered a flaw in the
WMM implementation in Broadcom wifi firmware. This could be
exploited by a nearby attacker to execute code on the wifi
microcontroller.
CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080,
CVE-2017-13081
Mathy Vanhoef of the imec-DistriNet research group of KU Leuven
discovered multiple vulnerabilities in the WPA protocol used for
authentication in wireless networks, dubbed "KRACK".
An attacker exploiting the vulnerabilities could force the
vulnerable system to reuse cryptographic session keys, enabling a
range of cryptographic attacks against the ciphers used in WPA1
and WPA2.
These vulnerabilities are only being fixed for certain Broadcom
wifi chips, and might still be present in firmware for other wifi
hardware.
For Debian 8 "Jessie", these problems have been fixed in version
20161130-4~deb8u1. This version also adds new firmware and packages
for use with Linux 4.9, and re-adds firmware-{adi,ralink} as
transitional packages.
We recommend that you upgrade your firmware-nonfree packages.
