[Bug 1918876] [NEW] sudo segfaults when /etc/sudoers has syntax error

[Owen Healy]

Public bug reported:

If /etc/sudoers contains the following (syntactically invalid) line:

    %sudo   ALL=(ALL:ALL) NOPASSWD ALL

the sudo command will segfault:

    $ sudo true
    [1]    12958 segmentation fault (core dumped)  sudo true

A better result would be to fail or warn with a syntax error.

Release: groovy
Architecture: amd64
sudo version: 1.9.1-1ubuntu1.1

** Affects: sudo (Ubuntu)
     Importance: Undecided
         Status: New
