========================================================================== Ubuntu Security Notice USN-3510-1 December 08, 2017
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel
Details:
Mohamed Ghannam discovered that a use-after-free vulnerability existed in the Netlink subsystem (XFRM) in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16939)
It was discovered that the Linux kernel did not properly handle copy-on- write of transparent huge pages. A local attacker could use this to cause a denial of service (application crashes) or possibly gain administrative privileges. (CVE-2017-1000405)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-137-generic 3.13.0-137.186 linux-image-3.13.0-137-generic-lpae 3.13.0-137.186 linux-image-3.13.0-137-lowlatency 3.13.0-137.186 linux-image-3.13.0-137-powerpc-e500 3.13.0-137.186 linux-image-3.13.0-137-powerpc-e500mc 3.13.0-137.186 linux-image-3.13.0-137-powerpc-smp 3.13.0-137.186 linux-image-3.13.0-137-powerpc64-emb 3.13.0-137.186 linux-image-3.13.0-137-powerpc64-smp 3.13.0-137.186 linux-image-generic 3.13.0.137.146 linux-image-generic-lpae 3.13.0.137.146 linux-image-lowlatency 3.13.0.137.146 linux-image-powerpc-e500 3.13.0.137.146 linux-image-powerpc-e500mc 3.13.0.137.146 linux-image-powerpc-smp 3.13.0.137.146 linux-image-powerpc64-emb 3.13.0.137.146 linux-image-powerpc64-smp 3.13.0.137.146
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.
