Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in Google Chrome's PDF handling. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code within the browser's sandbox by tricking a user into opening a specially crafted PDF file.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 152.0.7977.65. Detection involves checking the installed Chrome version. Use commands like 'google-chrome --version' on Linux or check 'chrome://settings/help' in the browser. If the version is below 152.0.7977.65, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your computer through a PDF file. Since it executes inside Chrome's sandbox, it may be limited but could still compromise your browser session or data. Users should update Chrome to the latest version to mitigate this risk.

Compliance Impact

This vulnerability does not directly impact compliance with GDPR, HIPAA, or similar standards as it is a technical flaw in Google Chrome's PDF handling. However, if exploited, it could lead to unauthorized code execution, potentially compromising data confidentiality or integrity, which may indirectly affect compliance.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the use after free vulnerability in PDF handling.
