Title

All manual page files must not have extended ACLs. (Cat III impact)

Discussion

If manual pages are compromised, misleading information could be inserted, causing actions that may compromise the system.

Check Content

Verify all manual page files have no extended ACLs. Check environment variable $MANPATH for full list of manpage locations. # echo $MANPATH Check for ACLs, note only a partial list is presented below. # ls -lLR /usr/share/man /usr/sfw/man /usr/sfw/share/man If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- [file with extended ACL]
