SV-38698r1_rule The /etc/netsvc.conf file must not have an extended ACL.

Vulnerability discussion

The /etc/netsvc.conf file is used to specify the ordering of name resolution for the sendmail command, alias resolution for the sendmail command, and host name resolution routines. Malicious changes could prevent the system from functioning correctly or compromise system security.

Check content

Verify there is no extended ACL on the /etc/netsvc.conf file. # aclget /etc/netsvc.conf If extended permissions are enabled, this is a finding.

Fix text

Remove the extended ACL from the /etc/nsswitch.conf file and disable extended permissions. #acledit /etc/netsvc.conf

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
