Denial of service in nVidia NVS

1) Denial of service

EUVDB-ID: #VU1112

Risk: High

CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2016-8808

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a local user to cause DoS condition or gain elevated privileges on the target system.
The weakness exists due to insufficient input validation  in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x70000d5. By sending a specially crafted index to an internal array, a local attacker can trigger denial of service or increase privileges.
Successful exploitation of the vulnerability may result in denial of service or privilege escalation.

Mitigation

Update Quadro and NVS to 342.00, 375.63.
Update GeForce to 375.63.
