Ubuntu Security Notice USN-3182-1
February 01, 2017

ntfs-3g vulnerability
==========================================================================

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

- - Ubuntu 16.10
- - Ubuntu 16.04 LTS

Summary:

NTFS-3G could be made to load kernel modules as an administrator.

Software Description:
- - ntfs-3g: read/write NTFS driver for FUSE

Details:

Jann Horn discovered that NTFS-3G incorrectly filtered environment variables
when using the modprobe utility. A local attacker could possibly use this issue
to load arbitrary kernel modules.

Update instructions:

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

Ubuntu 16.10:
  ntfs-3g                         1:2016.2.22AR.1-3ubuntu0.1

Ubuntu 16.04 LTS:
  ntfs-3g                         1:2015.3.14AR.1-1ubuntu0.1

In general, a standard system update will make all the necessary changes.
