    Package        : virglrenderer     Version        : 0.7.0-2+deb10u1     CVE ID         : CVE-2019-18388 CVE-2019-18389 CVE-2019-18390 CVE-2019-18391                      CVE-2020-8002 CVE-2020-8003 CVE-2022-0135     Debian Bug     : 946942 949954 1009073

    Several security vulnerabilities were discovered in virglrenderer, a virtual     GPU for KVM virtualization.

    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.

    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-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-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-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-2022-0135

        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.

    For Debian 10 buster, these problems have been fixed in version     0.7.0-2+deb10u1.

    We recommend that you upgrade your virglrenderer packages.
