Description Prasad Pandit 2016-12-20 12:08:14 UTC

Quick Emulator(Qemu) built with the Virtio GPU Device emulator support is
vulnerable to an out of bounds memory access issue. It could occur while
processing 'VIRTIO_GPU_CMD_GET_CAPSET' command.

A guest user/process could use this flaw to crash the Qemu process instance
on a host, resulting in DoS.
