when the "pwfeedback" option is enabled in sudoers that can lead
to a buffer overflow.  See https://www.sudo.ws/alerts/pwfeedback.html

Major changes between sudo 1.8.31 and 1.8.30

 * Fixed CVE-2019-18634, a buffer overflow when the "pwfeedback"
   sudoers option is enabled on systems with uni-directional pipes.

 * The "sudoedit_checkdir" option now treats a user-owned directory
   as writable, even if it does not have the write bit set at the
   time of check.  Symbolic links will no longer be followed by
   sudoedit in any user-owned directory.  Bug #912

 * Fixed sudoedit on macOS 10.15 and above where the root file system
   is mounted read-only.  Bug #913.

 * Fixed a crash introduced in sudo 1.8.30 when suspending sudo
   at the password prompt.  Bug #914.

 * Fixed compilation on systems where the mmap MAP_ANON flag
   is not available.  Bug #915.
