USN-2640-1: Linux kernel vulnerability

Ubuntu Security Notice USN-2640-1

15th June, 2015

linux vulnerability

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

  • Ubuntu 12.04 LTS

Summary

The system could be made to run programs as an administrator.

Software description

  • linux
    – Linux kernel

Details

Philip Pettersson discovered a privilege escalation when using overlayfs
mounts inside of user namespaces. A local user could exploit this flaw to
gain administrative privileges on the system.

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-86-generic-pae

3.2.0-86.123
linux-image-3.2.0-86-powerpc64-smp

3.2.0-86.123
linux-image-3.2.0-86-generic

3.2.0-86.123
linux-image-3.2.0-86-virtual

3.2.0-86.123
linux-image-3.2.0-86-omap

3.2.0-86.123
linux-image-3.2.0-86-powerpc-smp

3.2.0-86.123
linux-image-3.2.0-86-highbank

3.2.0-86.123

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
