Title
Files executed through a mail aliases file must not have extended ACLs. (Cat II impact)
Discussion
Excessive permissions on files executed through a mail alias file could result in modification by an unauthorized user, execution of malicious code, and/or system compromise.
Check Content
Examine the contents of the /etc/mail/aliases file. For each file referenced, check the permissions of the file. # ls -lL [file referenced from aliases] 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. # getfacl [file referenced from aliases] Remove each ACE returned. # setfacl -d [ACE] [file referenced from aliases]
