[Bug 501204] Re: sudo syntax error in /etc/sudoers due to #-- comment

[Benjamin Drung]

Thanks for reporting this issue and for providing steps to reproduce.

I tried to reproduce it on Ubuntu 22.04 (jammy) and added a
"#--ariel--#" comment line to my sudoers file. sudo correctly ignore it.
So I mark this bug as fixed.

Title:
  sudo syntax error in /etc/sudoers due to #-- comment

Status in sudo package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: sudo

  I put a few comments in /etc/sudoers where the '#' comment char is succeeded with --  as in:
  #--ariel--#

  result:  sudo won't work anymore.

      $ sudo echo OK
      >>> /etc/sudoers: syntax error near line 9 <<<
      >>> /etc/sudoers: syntax error near line 27 <<<
      sudo: parse error in /etc/sudoers near line 9
      sudo: no valid sudoers sources found, quitting

  putting a space between the '#' and '--' solves the problem.

  Comments should start with '#' only.
