The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3662-1 advisory.
It was discovered that the NVIDIA graphics drivers contained flaws in the kernel mode layer. A local attacker could use these issues to cause a denial of service or potentially escalate their privileges on the system.
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
