on the remote host is 12.1.x or 14.0.x prior to 14.2.3332.1000.
It is, therefore, affected by kernel memory disclosure vulnerability.
A specially crafted IRP request can cause disclosure of uninitialized memory.

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