Description Prasad Pandit 2017-02-08 10:15:07 UTC 
Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support
for the virtio GPU, is vulnerable to memory leakage issue. It
could occur when a guest invokes a 'VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING'
command.

A guest user/process could use this flaw to leak host memory leading to DoS.
