====================
The Xen netback implementation contains a couple of flaws which can
allow a guest to cause a DoS in the backend domain, potentially
affecting other domains in the system.
CVE-2013-0216 is a failure to sanity check the ring producer/consumer
pointers which can allow a guest to cause netback to loop for an
extended period preventing other work from occurring.
CVE-2013-0217 is a memory leak on an error path which is guest
triggerable.
The following series contains the fixes for these issues, as previously
included in Xen Security Advisory 39:
