Check Text ( C-43246r1_chk )
Check the file permissions for the MIB files.
# find / -name *mib* -o -name *MIB* | xargs ls -lL

If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.
Fix Text (F-39329r1_fix)
Remove the extended ACL from the file.
# setfacl --remove-all
