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.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - virglrenderer: out-of-bounds read in the vrend_blit_need_swizzle may lead to DoS (CVE-2019-18390)

  - 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. (CVE-2019-18388)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3232 advisory.

  - 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. (CVE-2019-18388)

  - 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-2019-18389)

  - 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-2019-18390)

  - 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-2019-18391)

  - 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-2020-8002)

  - 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-2020-8003)

  - An out-of-bounds write issue was found in the VirGL virtual OpenGL renderer (virglrenderer). This flaw     allows a malicious guest to create a specially crafted virgil resource and then issue a VIRTGPU_EXECBUFFER     ioctl, leading to a denial of service or possible code execution. (CVE-2022-0135)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
