Package : firmware-nonfree Version : 20161130-4~deb8u1 CVE ID : CVE-2016-0801 CVE-2017-0561 CVE-2017-9417 CVE-2017-13077 CVE-2017-13078 CVE-2017-13079 CVE-2017-13080 CVE-2017-13081 Debian Bug : 620066 724970 769633 774914 790061 793544 793874 795303 800090 800440 800820 801514 802970 803920 808792 816350 823402 823637 826996 832925 833355 833876 838038 838476 838858 841092 842762 854695 854907 856853 862458 869639 907320 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.
