Status changed to 'Confirmed' because the bug affects multiple users.

[Carl-Johan Sveningsson (cj-sveningsson)]

Umm, confirmed on Ubuntu 14.04.1 LTS, recently updated from 12... what's this about and how can I fix it? Seems harmless so far though.

cj@rocksteady:~$ sudo su minecraft -
[sudo] password for cj:
no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
minecraft@rocksteady:/mnt/data/home/cj$ script /dev/null
Script started, file is /dev/null
minecraft@rocksteady:/mnt/data/home/cj$ screen -dR

I realize I get some nutty memory leak before the other dude though. I'll investigate.

Edit: that memory leak was due to https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1257186, which fixed (by removing libpam-smbpass) leaves the original ioctl error :-/

This was working in Ubuntu 14.04 a few weeks ago. Did something change with bash recently, perhaps with the vulnerability that was announced? How can we fix this? I have a script that is broken now because of it.

Still an issue in 14.04. After enabling ldap-client su no longer works

Disregard my comment, it was due to UID mismatching
