<uumas>
Apparently ltsp5 logs anyone whose login shell isn't /bin/bash (or is /usr/bin/fish, didn't bother testing) in as root on clients. Took a moment to hunt that one down (one user logs in as root while everyone else is normal)
06:36
<alkisg>
uumas: huh, that sounds like a serious bug
06:36
distro/version?
06:36
<uumas>
Ubuntu bionic
06:36
<alkisg>
With the greek schools ppa?
06:37
<uumas>
Yeah
06:37
<alkisg>
Hrm
06:37
uumas: could you file a bug report about it in launchpad, but check [x] this is a security issue, so that it's not disclosed to non-developers?
06:38
!ltsp-bug
06:38
<ltsp>
ltsp-bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp
06:39
<uumas>
Sure. I'll need to test it further first so might take until evening or tomorrow. Might also have something to do with using FreeIPA for authentication, but idk...
06:39
<alkisg>
If freeipa is just on the server, then it's still an ltsp bug
06:39
<uumas>
Being root on a client isn't that big of a security issue though, right?
06:39
<alkisg>
If you tried to put freeipa on the client, then ok it might not be
06:39
<uumas>
Will have to test that
06:39
<alkisg>
uumas: well, one can install keyloggers and... :/
06:40
The last time LDM had such a problem, a CVE was issued
06:40
<uumas>
Well true
06:50gdi2k has left IRC (gdi2k!~gdi2k@58.69.160.28, Ping timeout: 272 seconds)

<uumas>
Was apparently much quicker to test than I thought. Submitted a report!
07:12
<alkisg>
uumas: do you have freeipa installed in the chroot/client?
07:14
<uumas>
They just use freeipa for authentication ie. just sssd installed. Also happened using a local user so I'd say it has nothing to do with that.
07:16
<alkisg>
uumas: so to reproduce, I'd just change install fish and change my shell to it, right?
07:16
<uumas>
Yes
07:17
<alkisg>
Ty; will try it
