1) Denial of service

EUVDB-ID: #VU1115

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-2016-8811

CWE-ID: CWE-120 - Buffer overflow

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 buffer overflow in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x7000170. By sending a specially crafted file, 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.
