The Xen Project reports :

Guests configured with PoD might be unstable, especially under load.
In an affected guest, an unprivileged guest user might be able to cause a guest crash, perhaps simply by applying load so as to cause heavy memory pressure within the guest.

This update fixes the following security issues :
