Ubuntu Security Notice USN-1918-1
July 29, 2013
linux-ti-omap4 vulnerability
============================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
Summary:
The system could be made to crash or run programs as an administrator.
Software Description:
- linux-ti-omap4: Linux kernel for OMAP4
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 12.10:
linux-image-3.5.0-229-omap4 3.5.0-229.42
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.
