Xen mishandling of the event channel validity constraint DoS (XSA-338))

A denial of service DoS vulnerability exists in Xen due to a mishandling of the constraint that once-valid event channels may not turn invalid. An unprivileged guest may be able to crash Xen, leading to a denial of service for the entire system. Note that Nessus has not tested for this issue but...
