========================================================================== Ubuntu Security Notice USN-3052-1 August 10, 2016
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 kernel.
Software Description: - linux: Linux kernel
Details:
It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4470)
Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-5243)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-93-generic 3.13.0-93.140 linux-image-3.13.0-93-generic-lpae 3.13.0-93.140 linux-image-3.13.0-93-lowlatency 3.13.0-93.140 linux-image-3.13.0-93-powerpc-e500 3.13.0-93.140 linux-image-3.13.0-93-powerpc-e500mc 3.13.0-93.140 linux-image-3.13.0-93-powerpc-smp 3.13.0-93.140 linux-image-3.13.0-93-powerpc64-emb 3.13.0-93.140 linux-image-3.13.0-93-powerpc64-smp 3.13.0-93.140
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.
