Title

Library files must have mode 0755 or less permissive. (Cat II impact)

Discussion

Unauthorized access could destroy the integrity of the library files.

Check Content

Open a terminal session and enter the following command to verify the permissions on library and framework files, all on one line. find /System/Library/Frameworks /Library/Frameworks /usr/lib /usr/local/lib -type f -perm +022 -exec stat -f %Lp:%N {} \; If any of the library files have a mode more permissive than 0755, this is a finding.

Fix Text

Open a terminal session and enter the following command to change the mode of library files to 0755 or less permissive. chmod 0755 <path/to/library-file> NOTE: Library files should have an extension of ".a" or ".so", possibly followed by a version number. Frameworks are directories that may already contain files with more restrictive permissions than 755 and thus should not have their modes changed to 755 recursively.
