COMPLETE Summary
All versions of NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape where a value passed from a user to the driver is used without validation as the size input to memcpy(), causing a buffer overflow, leading to denial of service or potential escalation of privileges.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| NASL id | NVIDIA_WIN_CVE_2016_8813.NASL |
| description | The version of the NVIDIA GPU display driver installed on the remote Windows host is 34x.x prior to 342.00, 367.x prior to 369.73, 367.x prior to 369.71 (GRID), or 375.x prior to 375.63. It is, therefore, affected by multiple vulnerabilities : - Multiple privilege escalation vulnerabilities exist in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to a NULL pointer dereference flaw. A local attacker can exploit this to cause a denial of service condition or an escalation of privileges. (CVE-2016-8813, CVE-2016-8814) - Multiple privilege escalation vulnerabilities exist in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper validation of user-supplied input used for the index to an array. A local attacker can exploit this to cause a denial of service condition or an escalation of privileges. (CVE-2016-8815, CVE-2016-8815) - A privilege escalation vulnerability exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper validation of user-supplied input to the memcpy() function. A local attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or an escalation of privileges. (CVE-2016-8817) - A privilege escalation vulnerability exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper validation of user-supplied input. A local attacker can exploit this to cause a denial of service condition or an escalation of privileges. (CVE-2016-8818) - A privilege escalation vulnerability exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper handling of objects in memory. A local attacker can exploit this to cause a denial of service condition or an escalation of privileges. (CVE-2016-8819) - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to a failure to check a function return value. A local attacker can exploit this to disclose sensitive information or cause a denial of service condition. (CVE-2016-8820) |
