Emergency reboot of Ubuntu workstations

Friday, September 17th, 2010

On Friday, September 17, at 22:00,  we will have to extraordinarily reboot our 64-bit Ubuntu workstations in order to deal with a nasty security issue. We’re sorry for the short notice but we’ve been unpleasantly surprised by this just as much as you have. If you’re reading this in time, please save all your data and log out if you can. Please note that also the terminal servers plimpy, plompy, plempy and plumpy (yes I know..) are affected. Thank you.

Linux kernel local privilege escalation

Tuesday, August 18th, 2009

In case you’ve been wondering about the slightly dubious announcements of the past few days: on Friday (2009/08/14) a local privilege escalation in all Linux kernels of the last 7 years was published, together with an exploit. Unfortunately no patched kernels were available by Friday late afternoon, which put us into an awkward position. Generally it is not our policy to be sneaky about security issues, but in this case we really did not want to attract malicious script kiddies. That’s why we decided to keep our announcements somewhat vague. By now the worst seems to be over and all machines have been rebooted with patched kernels.

We apologize for any confusion or service degradation this episode may have caused on your side.
