[Bug 2142721] Re: sudo-rs echos * for every character typed breaking historical security measures older than I am

[Mystica555]

Furthermore, if you want user friendliness, setup by default an askpass
solution that will pop up a GUI dialog for password input if within a
graphical session.

But seriously.

The easiest way to achieve both of our goals is simply distributing a
new sudoers template with the pwfeedback option enabled by default.

Title:
  sudo-rs echos * for every character typed breaking historical security
  measures older than I am

Status in rust-sudo-rs package in Ubuntu:
  Won't Fix

Bug description:
  Just upgraded 26.04 amd64v3 to sudo-rs 0.2.12-0ubuntu1

  Before this upgrade, as expected, typing a password in a terminal
  echos NOTHING.

  After this upgrade, I get STARS ECHOED.

  WHY?!

  This goes against DECADES of NOT ECHOING THE LENGTH OF THE PASSWORD TO
  SHOULDER SURFERS.

  FIX THIS.
