"The version of NVIDIA GeForce Experience installed on the remote Windows host
is prior to 3.20.2. It is, therefore, affected by a privilege escalation
vulnerability. An attacker with local system access may be able to exploit
this, by corrupting a system file, to gain privileged or administrator access
to the system.

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