Ubuntu Security Notice USN-1920-1
July 30, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
The system could be made to crash or run programs as an administrator.
- linux-ti-omap4: Linux kernel for OMAP4
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.
The problem can be corrected by updating your system to the following
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.
