"The remote Ubuntu 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the
USN-3904-1 advisory.

    It was discovered that the NVIDIA graphics drivers incorrectly handled the GPU performance counters. A
    local attacker could possibly use this issue to access the application data processed on the GPU.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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