6 issues skipped by the security teams:
- CVE-2019-18391: A heap-based buffer overflow in the vrend_renderer_transfer_write_iov function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service via VIRGL_CCMD_RESOURCE_INLINE_WRITE commands.
- CVE-2019-18389: A heap-based buffer overflow in the vrend_renderer_transfer_write_iov function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service, or QEMU guest-to-host escape and code execution, via VIRGL_CCMD_RESOURCE_INLINE_WRITE commands.
- CVE-2019-18390: An out-of-bounds read in the vrend_blit_need_swizzle function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service via VIRGL_CCMD_BLIT commands.
- CVE-2020-8003: A double-free vulnerability in vrend_renderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service by triggering texture allocation failure, because vrend_renderer_resource_allocated_texture is not an appropriate place for a free.
- CVE-2020-8002: A NULL pointer dereference in vrend_renderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service via commands that attempt to launch a grid without previously providing a Compute Shader (CS).
- CVE-2019-18388: A NULL pointer dereference in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service via malformed commands.
