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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 vulnerability is a use after free issue in PDFium, which is the PDF rendering engine used by Google Chrome. A use after free occurs when a program continues to use memory after it has been freed, potentially leading to corruption or arbitrary code execution. In this case, a remote attacker could exploit this by tricking a user into opening a specially crafted PDF file, allowing them to execute arbitrary code within the sandboxed environment of Chrome.

Detection Guidance

Detection requires checking the installed version of Google Chrome. If your version is prior to 151.0.7922.72, the system is vulnerable. Use commands like 'google-chrome --version' or 'apt list --installed | grep chrome' to verify the version.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your computer. Since it occurs through a crafted PDF file, simply opening a malicious file could trigger the exploit. The sandbox in Chrome limits the impact, but successful exploitation could still lead to unauthorized access or control of your system.

Compliance Impact

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

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later immediately. Disable PDF viewing in Chrome or use an alternative PDF reader until the update is applied. Avoid opening untrusted PDF files.
