Check: GEN007740
VMware ESX 3 Server:
GEN007740
(in version v1 r2)
Title
The IPv6 protocol handler must not be installed unless needed. (Cat II impact)
Discussion
IPv6 is the next generation of the Internet protocol. 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.
Check Content
If the IPv6 protocol handler is not available as an optional software package for the system, this is not applicable. If the system uses IPv6, this is not applicable. If the IPv6 protocol handler is installed, this is a finding.
Fix Text
Uninstall the IPv6 protocol handler from the system.
