Debian DLA-3232-1 : virglrenderer - LTS security update

high Nessus Plugin ID 168487

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

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.

Solution

Upgrade the virglrenderer packages.

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