Due to a vulnerabity in GNU C L Library that could allow for remote code execution CUIT administrators will need to patch and reboot all the Linux hosts today January 28th.
The reboot of all vulnerable hosts will occur in two waves. During the first wave the dev and test environments will be rebooted from 1:30 - 3:30. The second wave will begin at 5:30 and patch the production environments. We expect to be completed with all patching by 7pm.
During the production system patching wave, the reboots may temporarily affect access to major services provided or maintained by CUIT, including electronic mail, Columbia Webpages, CourseWorks, ARC and others. The impact to each individual services is expected to be minimal as each services is restarted this evening during the patching.
