Summary:

Due to the log4j vulnerability we will restart multiple systems.

Details:

Some days ago a vulnerability was found in log4j. This vulnerability hits all kind of software. At this moment not all pieces of software that are vulnerable are known. Furthermore multiple organisations, including BIT, are scanning for vulnerable hosts.
Today we will patch vulnerable software, restart software with mitigating measures and restart hosts for these hosts that during the day turn out to be vulnerable.
