Time not getting sync on XenServer with NTP

High NTP offset and jitter while delay is low. This can be seen with "ntpq -p". Offset is the time difference between the local server and remote Jitter is the difference between the last and current offset measurements, thus if it is high, it means that the offset is increasing more over time...

Gatecoin: API request signature can be reused with other parameters/data than the original in certain cases

If an attacker can intercept/see an API-request from a client who has a system-clock that is slightly ahead of the server time then the attacker can re-use the API request-signature towards the same URL but with a different payload. This can for some of the endpoint lead to serious vulnerabilitie...
