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 to 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.
