Linux Kernel Update

Friday, October 23rd, 2009

We installed new linux kernels for our systems and the machines need to be rebooted to run the new kernel. We will reboot the D-PHYS Linux Workstation "plimpy" this evening after 06:00 pm, not all the workstations. Please log out this evening before you go home, save all unsaved work and don't start any long running jobs.

The terminal server "plimpy" is affected as well, please save all your open documents and log out from your LTSP terminal. 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.

Beware of phishing e-mails

Wednesday, June 17th, 2009

Of course 'UPGRADE YOUR ETHZ E-Mail-Konto.' is a phishing attempt. And not a bad one at that. The German is halfway correct and they even used different From: and Reply-To: addresses. But still: no administrator worth her title would ever ask for a password. Please delete.
