Denial of service in nVidia NVS

1) Denial of service

EUVDB-ID: #VU1111

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-2016-8807

CWE-ID: CWE-121 - Stack-based 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 insufficient input validation  in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x10000e9. By sending a size input to memcpy(, a local attacker can trigger stack buffer overflow, leading to denial of service or privileges escalation.
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.

Vulnerable software versions
