Ubuntu Security Notice USN-1916-1
July 29, 2013

linux-lts-raring 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-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.
