Memory leak in the vrend_renderer_init_blit_ctx function in vrend_blitter.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRGL_CCMD_BLIT commands.

CVE-2017-5993 Virglrenderer: host memory leakage when initialising blitter context
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 tries to initialise blitter context via 'VIRGL_CCMD_BLIT' command.
A guest user/process could use this flaw to leak host memory resulting in DoS.
