========================================================================== Ubuntu Security Notice USN-3128-3 November 11, 2016
linux-snapdragon vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
The system could be made to crash under certain conditions.
Software Description: - linux-snapdragon: Linux kernel for Snapdragon Processors
Details:
Ondrej Kozina discovered that the keyring interface in the Linux kernel contained a buffer overflow when displaying timeout events via the /proc/keys interface. A local attacker could use this to cause a denial of service (system crash).
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-1035-snapdragon 4.4.0-1035.39 linux-image-snapdragon 4.4.0.1035.27
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.
