Description Wolfram R. Jarisch 2003-12-11 18:35:19 UTC
Description of problem: "up2date -u" does not always request root
privileges when logged in with ssh. Time since last request for
"up2date -u" may matter (, 2 minutes?). BUT: running up2date -u,
logging out, logging back in (all with ssh within a minute) would
allow someone else (using same username and passwd) to run up2date. I
guess this should not be.

Version-Release number of selected component (if applicable):
RedHat 9.0

How reproducible: elapsed time may matter, otherwise 90+%

Steps to Reproduce:
1.login with ssh. run "up2date -u" (answer root passwd). logout.
2.login again with ssh (within a minute?)
3.run "up2date -u" ... do not get request for root passwd
Actual results: root passwd not always needed to do privileged work
                may be a problem in other settings as well?

Expected results: should request root privileges EVERY time

Additional info: will keep watching this

up2date does no handling of aquiring root privs itself, thats
the userhelper/consolehelper utils from the "usermode" package
(and it sounds like in this case, the pam_timestamp setup).

reassigning to usermode

Workaround: put "sudo -k" in your .bash_logout. That should clear the
