6.9 - USN-1916-1

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-lts-raring: Linux hardware enablement kernel from Raring

Details:

Kees Cook discovered a format string vulnerability in the Broadcom B43 wireless driver for the Linux kernel. A local user could exploit this flaw to gain administrative privileges.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.8.0-27-generic 3.8.0-27.40~precise3

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.
