Denial of service in nVidia NVS

1) Denial of service

EUVDB-ID: #VU1128

Risk: Medium

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:Green]

CVE-ID: CVE-2016-8812

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: Yes

Description

The vulnerability allows a local user to cause D0S condition or obtain elevated privileges on the target system.
The weakness exists in the kernel mode layer (nvstreamkms.sys). By specially crafted executable paths a local attacker can trigger a stack buffer overflow, leading to a denial of service or escalation of privileges.
Successful exploitation of the vulnerability may result in denial of service or privilege escalation.

Mitigation

Update to version 2.11.4.125, 3.1.0.52.
