Ubuntu Security Notice USN-2661-1
July 07, 2015

linux-ti-omap4 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

The system could be made to expose sensitive information to local
applications.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

A race condition was discovered in the Linux kernel's file_handle size
verification. A local user could exploit this flaw to read potentially
sensative memory locations.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1467-omap4 3.2.0-1467.88

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.
