(in versions v1 r19 through v1 r13)
Title
The /etc/resolv.conf file must not have an extended ACL. (Cat II impact)
Discussion
The resolv.conf (or equivalent) file configures the system's DNS resolver. DNS is used to resolve host names to IP addresses. If DNS configuration is modified maliciously, host name resolution may fail or return incorrect information. DNS may be used by a variety of system security functions such as time synchronization, centralized authentication, and remote system logging.
Check Content
Verify /etc/resolv.conf has no extended ACL. # ls -lL /etc/resolv.conf 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/resolv.conf
