Title

The Transparent Inter-Process Communication (TIPC) protocol must be disabled or not installed. (Cat II impact)

Discussion

The Transparent Inter-Process Communication (TIPC) protocol is a relatively new cluster communications protocol developed by Ericsson. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the kernel to dynamically load a protocol handler by opening a socket using the protocol. Satisfies: SRG-OS-000096, SRG-OS-000510

Check Content

Verify the TIPC protocol handler package is not installed. # pkginfo | grep SUNWtipc If the TIPC protocol handler package is not installed, this is not a finding Verify the TIPC protocol handler is prevented from dynamic loading. # grep "exclude: tipc" /etc/system If no result is returned, this is a finding.

Fix Text

Remove the TIPC protocol handler package. # pkgrm SUNWtipc OR Prevent the TIPC protocol handler from dynamic loading. # echo "exclude: tipc" >> /etc/system
