Memory leak in the virgl_resource_attach_backing function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING commands.

Fixed by: http://git.qemu.org/?p=qemu.git;a=commit;h=33243031dad02d161225ba99d782616da133f689 (v2.9.0-rc0)
Marked as unimportant, since 1:2.8+dfsg-2 reverted the support for
virtio gpu (virglrenderer) and opengl, but the affected code is
still present.
