========================================================================== Ubuntu Security Notice USN-1914-1 July 29, 2013
linux 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: Linux kernel
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-3.2.0-51-generic 3.2.0-51.77 linux-image-3.2.0-51-generic-pae 3.2.0-51.77 linux-image-3.2.0-51-highbank 3.2.0-51.77 linux-image-3.2.0-51-omap 3.2.0-51.77 linux-image-3.2.0-51-powerpc-smp 3.2.0-51.77 linux-image-3.2.0-51-powerpc64-smp 3.2.0-51.77 linux-image-3.2.0-51-virtual 3.2.0-51.77
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.
