Troubleshooting Retries on Provisioned Virtual Machines

What is a retry? When a target streams a vDisk image, it does so by requesting blocks of data from the PVS server, which in turn replies with the requested data. This data is broken down into several packets called fragments. A retry occurs when a target device requests data from the PVS server a...

kernel: MTU value is not validated in IPv6 stack causing packet loss

It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking packet loss by setting an invalid MTU value, for example, via a NetworkManager...
