USN-3034-2: Linux kernel (Trusty HWE) vulnerability Ubuntu Security Notice USN-3034-2 14th July, 2016 linux-lts-trusty vulnerability A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.04 LTS Summary The system could be made to crash under certain conditions. Software description linux-lts-trusty – Linux hardware enablement kernel from Trusty for Precise Details USN-3034-1 fixed a vulnerability in the Linux kernel for Ubuntu 14.04LTS. This update provides the corresponding updates for the LinuxHardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu12.04 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 12.04 LTS: [ more… ]
