Title

SLEM 5 library files must have mode 755 or less permissive. (Cat II impact)

Discussion

If SLEM 5 were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. This requirement applies to SLEM 5 with software libraries that are accessible and configurable, as in the case of interpreted languages. Software libraries also include privileged programs which execute with escalated privileges. Only qualified and authorized individuals must be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications.

Check Content

Verify the systemwide shared library files contained in the directories "/lib", "/lib64", "/usr/lib", and "/usr/lib64" have mode 0755 or less permissive. Check that the systemwide shared library files have mode 0755 or less permissive with the following command: > sudo find /lib /lib64 /usr/lib /usr/lib64 -type f -name '*.so*' -perm /022 -exec stat -c "%n %a" {} + If any output is returned, this is a finding.

Fix Text

Configure the systemwide shared library files contained in the directories "/lib", "/lib64", "/usr/lib", and "/usr/lib64" have mode 0755 or less permissive with the following command. > sudo transactional-update shell > sudo find /lib /lib64 /usr/lib /usr/lib64 -type f -name '*.so*' -perm /022 -exec chmod go-w {} + > exit > sudo reboot
