USN-3036-1: Linux kernel (Utopic HWE) vulnerability Ubuntu Security Notice USN-3036-1 14th July, 2016 linux-lts-utopic vulnerability A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 LTS Summary The system could be made to crash under certain conditions. Software description linux-lts-utopic – Linux hardware enablement kernel from Utopic for Trusty Details Jan Stancek discovered that the Linux kernel's memory manager did notproperly handle moving pages mapped by the asynchronous I/O (AIO) ringbuffer to the other nodes. A local attacker could use this to cause adenial of service (system crash). Update instructions The problem can be corrected by updating your system to the following package version: Ubuntu 14.04 LTS: linux-image-3.16.0-77-powerpc-smp 3.16.0-77.99~14.04.1 linux-image-3.16.0-77-powerpc-e500mc 3.16.0-77.99~14.04.1 linux-image-3.16.0-77-powerpc64-smp 3.16.0-77.99~14.04.1 linux-image-3.16.0-77-generic 3.16.0-77.99~14.04.1 linux-image-3.16.0-77-generic-lpae 3.16.0-77.99~14.04.1 linux-image-3.16.0-77-powerpc64-emb 3.16.0-77.99~14.04.1 linux-image-3.16.0-77-lowlatency 3.16.0-77.99~14.04.1 To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
