USN-3035-3: Linux kernel (Wily HWE) vulnerability Ubuntu Security Notice USN-3035-3 14th July, 2016 linux-lts-wily 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-wily – Linux hardware enablement kernel from Wily for Trusty Details USN-3035-1 fixed vulnerabilities in the Linux kernel for Ubuntu 15.10.This update provides the corresponding updates for the Linux HardwareEnablement (HWE) kernel from Ubuntu 15.10 for Ubuntu 14.04 LTS. 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-4.2.0-42-powerpc64-smp 4.2.0-42.49~14.04.1 [ more… ]
