Upgrading Red Hat 6.6 servers to newer versions with Data Loss Prevention (DLP) installed results in an error. (DLP 14.X - 15.X)
After the upgrade sshd on all of the upgraded servers stops working with an error pointing to the DLP 'libz.so.1' module.
Starting sshd gives the following error:
"Starting sshd: /usrsbin/sshd: error while loading shared libraries:
libz.so.1: failed to map segment from shared object: Permission denied".
Data Loss Prevention 14.x
Data Loss Prevention 15.x
This error can be caused if SELinux is enabled on the server or is not set to "permissive"
Disable SELinux or set it to "permissive". If set to disabled; the system will need to be rebooted to apply the changes.
