========================================================================== Ubuntu Security Notice USN-3107-2 October 24, 2016 linux-raspi2 vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.10 Summary: The system could be made to run programs as an administrator. Software Description: - linux-raspi2: Linux kernel for Raspberry Pi 2 Details: It was discovered that a race condition existed in the memory manager of the Linux kernel when handling copy-on-write breakage of private read-only memory mappings. A local attacker could use this to gain administrative privileges. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.10: linux-image-4.8.0-1017-raspi2 4.8.0-1017.20 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.
