USN-3344-1: Linux kernel vulnerabilities Ubuntu Security Notice USN-3344-1 29th June, 2017 linux, linux-aws, linux-gke, linux-raspi2, linux-snapdragon vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 16.04 LTS Summary Several security issues were fixed in the Linux kernel. Software description linux – Linux kernel linux-aws – Linux kernel for Amazon Web Services (AWS) systems linux-gke – Linux kernel for Google Container Engine (GKE) systems linux-raspi2 – Linux kernel for Raspberry Pi 2 linux-snapdragon – Linux kernel for Snapdragon processors Details USN 3328-1 fixed a vulnerability in the Linux kernel. However, thatfix introduced regressions for some Java applications. This updateaddresses the issue. We apologize for the inconvenience. Roee Hay discovered that the parallel port printer driver in the Linuxkernel did not properly bounds check passed arguments. A local attackerwith write access to the kernel command line arguments could [ more… ]

USN-3344-2: Linux kernel (Xenial HWE) vulnerabilities Ubuntu Security Notice USN-3344-2 29th June, 2017 linux-lts-xenial vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 LTS Summary Several security issues were fixed in the Linux kernel.
