Discussion

Unauthorized access could destroy the integrity of the library files.

Check Content

Verify system libraries have no extended ACLs.
# ls -lL /usr/lib/* /usr/lib64/* /lib/* /lib64/* | grep "+ "
If the permissions include a '+', the file has an extended ACL and has not been approved by the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file.
# setfacl --remove-all /usr/lib/* /usr/lib64/* /lib/* /lib64/*
