The remote FreeBSD host is missing one or more security-related
Ian Jackson reports on the debian-security mailinglist :
When a block device read or write request is made by the guest,
nothing checks that the request is within the range supported by the
backend, but the code in the backend typically assumes that the
request is sensible.
Depending on the backend, this can allow the guest to read and write
arbitrary memory locations in qemu, and possibly gain control over the
qemu process, escaping from the emulation/virtualisation.
