Denial Of Service (DoS)

The Simple Protocol for Independent Computing Environments (SPICE) is vulnerable to Denial Of Service (DoS). It was found that the libspice component of QEMU-KVM on the host could be forced to perform certain memory management operations on memory addresses controlled by a guest. A privileged guest user could use this flaw to crash the guest (denial of service) or, possibly, escalate their privileges on the host.
