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

Check the group ownership of the /etc/netcsvc.conf file. Procedure: # ls -lL /etc/netsvc.conf If the file is not group-owned by bin, sys, or system, this is a finding.

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.
