Ubuntu 3641-2: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: linux-image-3.13.0-147-generic 3.13.0-147.196~precise1 linux-image-3.13.0-147-generic-lpae 3.13.0-147.196~precise1 linux-image-3.2.0-134-generic 3.2.0-134.180 linux-image-3.2.0-134-generic-pae 3.2.0-134.180 linux-image-3.2.0-134-highbank 3.2.0-134.180 linux-image-3.2.0-134-omap 3.2.0-134.180 linux-image-3.2.0-134-powerpc-smp 3.2.0-134.180 linux-image-3.2.0-134-powerpc64-smp 3.2.0-134.180 linux-image-3.2.0-134-virtual 3.2.0-134.180 linux-image-generic 3.2.0.134.149 linux-image-generic-lpae-lts-trusty 3.13.0.147.138 linux-image-generic-lts-trusty 3.13.0.147.138 linux-image-generic-pae 3.2.0.134.149 linux-image-highbank 3.2.0.134.149 linux-image-omap 3.2.0.134.149 linux-image-powerpc 3.2.0.134.149 linux-image-powerpc-smp 3.2.0.134.149 linux-image-powerpc64-smp 3.2.0.134.149 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
