Important Security Announcement

February 13, 2008

Due to the potential risk of the recent security vulnerability, the Lab staff will need to reinstall all Linux machines that are vulnerable. We will be doing the re-installations tomorrow, and possibly Friday. The re-installations will take about 1-2 hours per machine, depending on the network and server loads. We would like to start as early as possible. We will first install all machines that are not currently logged in. If there is a user logged in, we will attempt to make contact, but if we do not get a timely response we will need to reinstall.

We will make an attempt to copy any data stored in temporary areas to a central location. If you know that you have temporary data that needs to be moved, please copy it to another location such as /usr/xtmp (see /usr/project/xtmp/README_XTMP for more information) as soon as possible.

We appreciate your understanding, and apologize for the short notice.
