Weave Net clusters susceptible to MitM attacks via IPv6 rogue router advertisements

Impact An attacker able to run a process as root in a container is able to respond to DNS requests from the host and thereby insert themselves as a fake service. In a cluster with an IPv4 internal network, if IPv6 is not totally disabled on the host via ipv6.disable=1 on the kernel cmdline, it wi...

What is an IP address? Do I need one?

An IP address tells computers how to find a certain device within a computer network. An IP address is like an address label for information packets. For each network your computer is connected to, it has a unique IP address on that network. So, one device can have several IP addresses at the sam...
