Discussion

Excessive permissions on the alias files may permit unauthorized modification. If an alias file is modified by an unauthorized user, they may modify the file to run malicious code or redirect email.

Check Content

Check the permissions of the alias files:

# ls -lL /etc/aliases
# ls -lL /etc/aliases.db

If the files have a mode more permissive than "0644", this is a finding.

Fix Text

Change the mode of the alias files to "0644":

# chmod 0644 /etc/aliases /etc/aliases.db
