CVE-2017-5993 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream virglrenderer package and not the virglrenderer package as distributed by Ubuntu.
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.
