Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a
malicious guest can cause xenstored to use a wrong pointer during node
creation in an error path, resulting in a crash of xenstored or a memory
corruption in xenstored causing further damage. Entering the error path can
be controlled by the guest e.g. by exceeding the quota value of maximum
nodes per domain.
