A remote code execution vulnerability in the Broadcom Wi-Fi firmware could enable a remote attacker to execute arbitrary code within the context of the Wi-Fi SoC. This issue is rated as Critical due to the possibility of remote code execution in the context of the Wi-Fi SoC. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-34199105. References: B-RB#110814.

According to the versions of the linux-firmware packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - Broadcom BCM43xx Wi-Fi chips allow remote attackers to     execute arbitrary code via unspecified vectors, aka the     'Broadpwn' issue.(CVE-2017-9417)

  - A remote code execution vulnerability in the Broadcom     Wi-Fi firmware could enable a remote attacker to     execute arbitrary code within the context of the Wi-Fi     SoC. This issue is rated as Critical due to the     possibility of remote code execution in the context of     the Wi-Fi SoC. Product: Android. Versions: Kernel-3.10,     Kernel-3.18. Android ID: A-34199105. References:
    B-RB#110814.(CVE-2017-0561)

  - The Broadcom Wi-Fi driver in the kernel in Android 4.x     before 4.4.4, 5.x before 5.1.1 LMY49G, and 6.x before     2016-02-01 allows remote attackers to execute arbitrary     code or cause a denial of service (memory corruption)     via crafted wireless control message packets, aka     internal bug 25662029.(CVE-2016-0801)

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.
