Ubuntu 12.04 LTS USN-1915-1 Critical: Broadcom B43 Driver Exploit

The system could be made to crash or run programs as an administrator.. =========================================================================Ubuntu Security Notice USN-1915-1 July 29, 2013 linux-lts-quantal 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-quantal: Linux hardware enablement kernel from Quantal 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-3.5.0-37-generic 3.5.0-37.58~precise1 After a standard system update you need to reboot your computer to make all the necessary changes.
