InformationThe nosuid mount option specifies that the filesystem cannot contain setuid files.
Since the /var filesystem is only intended for temporary dynamic data, set this option to ensure that users cannot create setuid files in /var.
SolutionRun the following command to remount /var :
# mount -o remount,nosuid /var
/etc is stateless on Container-Optimized OS. Therefore, /etc cannot be used to make these changes persistent across reboots. The steps mentioned above needs to be performed after every boot.
