This update for virglrenderer fixes the following issues :

  - CVE-2019-18388: Fixed a NULL pointer dereference which     could have led to denial of service (bsc#1159479).

  - CVE-2019-18390: Fixed an out of bound read which could     have led to denial of service (bsc#1159478).

  - CVE-2019-18389: Fixed a heap buffer overflow which could     have led to guest escape or denial of service     (bsc#1159482).

  - CVE-2019-18391: Fixed a heap based buffer overflow which     could have led to guest escape or denial of service     (bsc#1159486). 

This update was imported from the SUSE:SLE-15:Update update project.

According to the versions of the virglrenderer packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the virglrenderer package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A heap-based buffer overflow flaw was found in     virglrenderer. The vrend_renderer_transfer_write_iov     function allows guest OS users to cause a denial of     service or a QEMU guest-to-host escape with code     execution. The highest threat from this vulnerability     is to data confidentiality and integrity as well as to     system availability.(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)

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.
