Description Vishal Gaikwad 2010-08-26 11:07:20 UTC 
Description of problem:
Using the Runas_Alias rule vis visudo seems to ne ignored.

Version-Release number of selected component (if applicable):
sudo-1.7.2p1-5.el5

How reproducible:
Always

Steps to Reproduce:
1) Create three user/group "a", "b", "c"

2) Run visudo command to add following lines:

User_Alias OK_GROUP = %a
Runas_Alias OK_RUNAS_GROUP = %b, %c
OK_GROUP ALL = (OK_RUNAS_GROUP) ALL

3) Run as user "a"
 
Actual results:
# sudo -g b ls /etc
Sorry, user a is not allowed to execute '/bin/ls /etc' as a:b on localhost.

Expected results:
$ sudo -g b ls /etc/
a2ps.cfg               conman.conf       firmware              init.d          ltrace.conf     ntp             rc0.d                    screenrc           tftpd.rules

Additional info:

A workaround is to use the following rule in visudo:

%a ALL = (:b, c) ALL
Comment 2 RHEL Program Management 2011-05-31 15:31:25 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

The attached patch adds interpretation of USERGROUP entries in the _runaslist_matches(user_list, group_list) function. To fix the second issue, it changes the handling of a resolved alias in the group check loop (passes it as a group list, not as an user list).

Stripped down patch. The case with %group syntax is not a bug (http://www.sudo.ws/pipermail/sudo-workers/2011-October/000699.html).
