  "details": "Any guest issuing a Xenstore command accessing a node using the (illegal) node path \"/local/domain/\", will crash xenstored due to a clobbered error indicator in xenstored when verifying the node path.  Note that the crash is forced via a failing assert() statement in xenstored. In case xenstored is being built with NDEBUG #defined, an unprivileged guest trying to access the node path \"/local/domain/\" will result in it no longer being serviced by xenstored, other guests (including dom0) will still be serviced, but xenstored will use up all cpu time it can get.",
