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:
