Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

The Xen Project reports :

A guest can submit virtio requests without bothering to wait for
completion and is therefore not bound by virtqueue size...

A malicious guest administrator can cause unbounded memory allocation
in QEMU, which can cause an Out-of-Memory condition in the domain
running qemu. Thus, a malicious guest administrator can cause a denial
of service affecting the whole host.
