Bug Description

Binary package hint: sobby

This was asked on the ubuntu-users mailing list:

To check this, I installed sobby and this was what I found:

Immediately after installation
bladernr@klaatu:~/.xchat2/xchatlogs$ ps aux |grep sobby
root 13000 0.0 0.0 62828 3588 ? S 17:52 0:00 /usr/bin/sobby

And a restart...
bladernr@klaatu:~/.xchat2/xchatlogs$ sudo service sobby restart
 * Stopping sobby [ OK ]
 * Starting sobby [ OK ]
bladernr@klaatu:~/.xchat2/xchatlogs$ ps aux |grep sobby
root 13555 3.0 0.0 62828 3580 ? S 18:02 0:00 /usr/bin/sobby

I'm not sure what the compromise potential is for sobby, but I really do NOT like services like this running as root. Am I crazy, or shouldn't sobby be running as a non-privileged user like other internet accessible services?

Agreed that sobby should not run as root; another useful thing to do would be to develop an AppArmor profile for it.

FWIW, that's the reason I rejected the init script in Debian. Of course it's not that difficult to create a seperate user for it in the maintainer script, but nobody did that yet.

I think calling it a security vulnerability is too harsh, there hasn't been any exploit in Sobby until now. It's unnecessary, though. I'll take care of it in Debian by providing an init script that uses a system user for Sobby, with proper usage of session serialization too.
