"The NVIDIA GPU display driver software on the remote Windows host is missing a security update. It is, therefore,
affected by multiple vulnerabilities:

  - An unspecified vulnerability exists in the kernel mode layer (nvvlddmkm.sys) handler for DxgkDdiEscape due to
    improper synchronization of shared data. An authenticated, local attacker can exploit this, to cause a denial of
    service, gain elevated privileges or to disclose potentially sensitive information. (CVE-2019-5675)

  - A binary planting vulnerability exists due to improper path or signature validation. An authenticated, local
    attacker can exploit this, via code execution to gain elevated privileges. (CVE-2019-5676)

  - A memory corruption vulnerability exists in the kernel mode layer (nvlddmkm.sys) handler for DeviceIoControl. An
    authenticated, local attacker can exploit this, to cause a denial of service condition. (CVE-2019-5677)");
