Summary

NVIDIA Windows GPU Display Driver contains a vulnerability in the kernel mode layer handler for DxgkDdiEscape in which the software uses a sequential operation to read from or write to a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer, which may lead to denial of service or escalation of privileges.

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.

descriptionThe NVIDIA GPU display driver software on the remote host is missing a security update. It is, therefore, affected by multiple vulnerabilities: - A vulnerability in the 3D vision component in which the stereo service software, when opening a file, does not check for hard links. This behavior may lead to code execution, denial of service or escalation of privileges. (CVE-2019-5665) - A vulnerability in the kernel mode layer (nvlddmkm.sys) create context command DDI DxgkDdiCreateContext in which the product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array, which may lead to denial of service or escalation of privileges. (CVE-2019-5666) - A vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiSetRootPageTable in which the application dereferences a pointer that it expects to be valid, but is NULL, which may lead to code execution, denial of service or escalation of privileges. (CVE-2019-5667) It is also affected by additional vulnerabilities including denial of service, privilege escalation, code execution, and information disclosure vulnerabilities. See the vendor advisory for details.
