Title
The alias file must not have an extended ACL. (Cat II impact)
Discussion
Excessive permissions on the aliases file may permit unauthorized modification. If the alias file is modified by an unauthorized user, they may modify the file to run malicious code or redirect e-mail.
Check Content
Check the permissions of the /etc/mail/aliases file. # ls -lL /etc/mail/aliases If the permissions include a "+", the file has an extended ACL, this is a finding.
Fix Text
Remove the optional ACL from the file. # chacl -z /etc/mail/aliases
