Description Andrew Taylor 2003-12-05 13:06:47 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a)

Description of problem:
The rwhod daemon has the ability to drop root privileges on its writer
process.  We might as well take advantage of this capability and run
it as a non-priviledged user.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Run rwhod.

Actual Results:  Runs as root.

Expected Results:  The writer process should be a non-priviledged user.

sysv init file changes to run rwhod as a non-privileged user

These patches make rwhod run the writer process as a new user called "rwhod".

As few notes:
the uid for rwhod is 49, which I chose at random.  It doesn't seem to conflict
with anything I've been able to find.  Is there a registry for system uids

Also, if an existing rwho RPM is updated, any files in /var/spool/rwho owned by
root will not be writable by rwhod, effectively freezing the rwho information
for those hosts in time.  Perhaps the spec file should do a chown?

Sounds like a good idea.

Investigating and discussing with folks here.

Read ya, Phil

Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
Comment 5 John Thacker 2006-10-25 16:27:23 EDT
Closing per previous comment and lack of response.  Also note that FC1 and FC2
are no longer supported even by Fedora Legacy.
