Ubuntu 1644-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.2.0-34-generic 3.2.0-34.53 linux-image-3.2.0-34-generic-pae 3.2.0-34.53 linux-image-3.2.0-34-highbank 3.2.0-34.53 linux-image-3.2.0-34-omap 3.2.0-34.53 linux-image-3.2.0-34-powerpc-smp 3.2.0-34.53 linux-image-3.2.0-34-powerpc64-smp 3.2.0-34.53 linux-image-3.2.0-34-virtual 3.2.0-34.53 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
