Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 20.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4689-4 advisory.

- NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape or IOCTL in which user-mode clients can access legacy privileged APIs, which may lead to denial of service, escalation of privileges, and information disclosure. (CVE-2021-1052)

- NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape or IOCTL in which improper validation of a user pointer may lead to denial of service. (CVE-2021-1053)

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