Red Hat Bugzilla – Bug 584899
PackageKit allows non-root users to install software updates
Last modified: 2010-11-11 10:23:58 EST
Description of problem:
Non-root users are able to install updated software packages without being prompted for root credentials.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RHEL6beta1
2. System > Administration > Software Update
Non-root users are able to update system software.
Root credentials would be required to update system software.
Do we really want to allow non-root users to install system updates by default.
Seems related to this bug in F12:
This is clearly a Fedora "feature" that must not be allowed in an Enterprise class OS.
I trust that this bug will be squashed, immediately.
If folks remember, this was really almost identical to
which made slashdot and distrowatch. While, as the developer says, there is a difference between updating already installed packages vs. installing previously uninstalled packages, this is simply unacceptable for many people (e.g., the last person to post in the Fedora bug that Ned mentions.)
I don't believe that even Windows allows this

I didn't read that bug in it's entirety, but one thing I'd like to point out that I didn't see mentioned is that this bug doesn't just apply to trusted Red Hat repositories, but applies to *all* (signed) repositories.
Given that an administrator might trust content from varying repositories to different extents (do you trust all your 3rd party repos to the same extent as you trust rhel/updates?), I'm not convinced I would want non-root users to be able to install updates by default that may potentially break things (*cough* ClamAV breaks every time it's updated!) and then not have the required privileges (or expertise) to fix what has broken.
IMHO ultimately this is a decision for the system administrator to make and the default policy should be one of caution as was previously the case. I just find it somewhat strange to see this "feature" in a release that also brings SELinux advancements allowing system administrators to further restrict users. It seems like pulling in two completely opposite directions.

- Use more secure defaults to only allow the root user to update the system.
- Resolves: #584899
Reproducer in description, expected behaviour: user should obtain pk password dialog window.
Expected behaviour verified on PackageKit-0.5.8-6.el6.
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
