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

Check the mode of library files. Procedure: # DIRS="/usr/lib /usr/lib64 /lib /lib64";for DIR in $DIRS;do find $DIR -type f -perm +022 -exec stat -c %a:%n {} \;;done This will return the octal permissions and name of all group or world writable files. If any file listed is world or group writable (either or both of the 2 lowest order digits contain a 2, 3 or 6), this is a finding.

Fix Text

Change the mode of library files to 0755 or less permissive. Procedure (example): # chmod go-w </path/to/library-file> Note: Library files should have an extension of ".a" or a ".so" extension, possibly followed by a version number.
