USN-3248-1: Linux kernel vulnerability Ubuntu Security Notice USN-3248-1 29th March, 2017 linux, linux-ti-omap4 vulnerability A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.04 LTS Summary The system could be made to crash or run programs as an administrator. Software description linux – Linux kernel linux-ti-omap4 – Linux kernel for OMAP4 Details It was discovered that the xfrm framework for transforming packets in theLinux kernel did not properly validate data received from user space. Alocal attacker could use this to cause a denial of service (system crash)or execute arbitrary code with administrative privileges. Update instructions The problem can be corrected by updating your system to the following package version: Ubuntu 12.04 LTS: linux-image-powerpc-smp 3.2.0.125.140 linux-image-3.2.0-125-generic-pae 3.2.0-125.168 linux-image-omap4 3.2.0.1503.98 linux-image-3.2.0-125-powerpc64-smp 3.2.0-125.168 linux-image-generic 3.2.0.125.140 linux-image-3.2.0-125-virtual 3.2.0-125.168 linux-image-generic-pae 3.2.0.125.140 linux-image-highbank 3.2.0.125.140 linux-image-3.2.0-125-generic 3.2.0-125.168 linux-image-3.2.0-125-omap 3.2.0-125.168 linux-image-3.2.0-125-powerpc-smp 3.2.0-125.168 linux-image-powerpc64-smp 3.2.0.125.140 linux-image-omap [ more… ]
