1.8.11. Therefore this bug is fixed since Ubuntu 16.04 (xenial).

Title:
  foregrounding a sudo'd vim will sometimes break terminal state

Status in sudo:
  Unknown
Status in sudo package in Ubuntu:
  Fix Released

Bug description:
  See this bug:
  http://www.sudo.ws/bugs/show_bug.cgi?id=649

  Started on Ubuntu/Trusty since it has a sudo after 1.8.7, (precise has
  1.8.3).

  Steps to reproduce:

  - take a local machine with a recent sudo (after 1.8.7)
  - sudo vi
  - ^Z (control-Z)
  - fg
  - repeat ^Z and fg until the fg fails and the screen is partially cleared
  - now a second fg wil open vim with a broken terminal state:
    arrow keys will render the escape sequences and other nastiness

  Fix is provided upstream, but author is currently figuring out why it
  breaks.

  Cheers,
