Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04

Summary:

The system could be made to run programs as an administrator.

Software Description: - linux: Linux kernel

Details:

An flaw was discovered in the Linux kernel's perf_events interface. A local user could exploit this flaw to escalate privileges on the system.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.04:
linux-image-3.8.0-21-generic 3.8.0-21.32

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.
