vim vulnerability
==========================================================================

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Vim could be made run programs as your login if it opened a specially
crafted file.

Software Description:
- vim: Vi IMproved - enhanced vi editor

Details:

Florian Larysch discovered that the Vim text editor did not properly
validate values for the 'filetype', 'syntax', and 'keymap' options. An
attacker could trick a user into opening a file with specially crafted
modelines and possibly execute arbitrary code with the user's privileges.
