USN-1930-1: Linux kernel (OMAP4) vulnerabilities

Releases

• Ubuntu 12.04

Packages

• linux-ti-omap4 - Linux kernel for OMAP4

Details

An information leak was discovered in the Linux kernel's fanotify
interface. A local user could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2013-2148)

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. (CVE-2013-2852)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04

• linux-image-3.2.0-1436-omap4 - 3.2.0-1436.55

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.
