========================================================================== Ubuntu Security Notice USN-3419-2 September 18, 2017
linux-hwe vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-hwe: Linux hardware enablement (HWE) kernel
Details:
USN-3419-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.04. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS.
It was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-1000251)
It was discovered that a buffer overflow existed in the Broadcom FullMAC WLAN driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7541)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.10.0-35-generic 4.10.0-35.39~16.04.1 linux-image-4.10.0-35-generic-lpae 4.10.0-35.39~16.04.1 linux-image-4.10.0-35-lowlatency 4.10.0-35.39~16.04.1 linux-image-generic-hwe-16.04 4.10.0.35.37 linux-image-generic-lpae-hwe-16.04 4.10.0.35.37 linux-image-lowlatency-hwe-16.04 4.10.0.35.37
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
