USN-3128-2: Linux kernel (Xenial HWE) vulnerability Ubuntu Security Notice USN-3128-2 11th November, 2016 linux-lts-xenial 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-xenial – Linux hardware enablement kernel from Xenial for Trusty Details USN-3128-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04LTS. This update provides the corresponding updates for the LinuxHardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu14.04 LTS. Ondrej Kozina discovered that the keyring interface in the Linux kernelcontained a buffer overflow when displaying timeout events via the/proc/keys interface. A local attacker could use this to cause a denial ofservice (system crash). Update instructions The problem can be corrected by updating your system to the following package version: Ubuntu 14.04 LTS: linux-image-powerpc-smp-lts-xenial 4.4.0.47.34 linux-image-4.4.0-47-powerpc64-emb 4.4.0-47.68~14.04.1 linux-image-4.4.0-47-lowlatency [ more… ]
