Description Karel Srot 2012-09-13 05:47:20 UTC 
Description of problem:

!<user> shout match to all users different from <user> but it doesn't seem to work and this patters seem to be ignored


Version-Release number of selected component (if applicable):
sudo-1.7.4p5-13.el6_3.x86_64

How reproducible:
always

Steps to Reproduce:
1. add test user
2. update sudoers with:
user  ALL=(ALL)   NOPASSWD: ALL
Defaults !requiretty        # actually not necessary, this is the default
Defaults:!root requiretty    # require tty for all non-root users
3. login as test user and add this into user's crontab (crontab -e)
* * * * *  /usr/bin/sudo id &> /tmp/id


Actual results:
every minute /tmp/id is updated with the output od the "id" command. This is not correct because cron jobs don't have tty and therefore we should see just the message similar to "sorry, you need tty"


Same situation on RHEL5 with sudo-1.7.2p1-21.el5

Comment 3 Karel Srot 2012-09-27 06:26:13 UTC 
Thank you. Maybe we can keep this bug open as a request for adding such an explanation into RH shipped sudo.
Comment 6 RHEL Program Management 2012-12-14 06:54:27 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
