Vulnerability discussion

The Reliable Datagram Sockets (RDS) protocol is a relatively new protocol developed by Oracle for communication between the nodes of a cluster. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the system to dynamically load a protocol handler by opening a socket using the protocol.

Check content

Ask the SA if RDS is required by application software running on the system. If so, this is not applicable. Verify the RDS protocol handler is not installed. # pkginfo | grep SUNWrds If no results are returned, this is not a finding. Verify the RDS protocol handler is prevented from dynamic loading. # grep "exclude: rds" /etc/system If no result is returned, this is a finding.

Fix text

Remove the RDS protocol handler package. # pkgrm SUNWrds OR Prevent the RDS protocol handler from dynamic loading. # echo "exclude: rds" >> /etc/system

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.
