Attack-Flow Graph

Executive Summary

This vulnerability is a memory corruption issue in the Fonts component of Google Chrome versions before 156.0.8078.47. It allows a remote attacker to read memory inside the browser's sandbox by tricking a user into visiting a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 156.0.8078.47. To detect it, check your Chrome version by running chrome://version/ in the browser. If your version is below 156.0.8078.47, update Chrome immediately. No direct network or system commands are provided in the CVE details for detection.

Impact Analysis

If exploited, this vulnerability could allow an attacker to access sensitive data in memory, potentially leading to information disclosure. However, the impact is limited because the attacker must first convince the user to visit a malicious page and the memory access is restricted to the sandboxed environment.

Compliance Impact

This vulnerability involves memory corruption in Google Chrome's Fonts component, allowing a remote attacker to read memory inside the sandbox via a crafted HTML page. While the CVSS score is Low (6.5), such memory corruption issues could potentially lead to unauthorized data access, which may impact compliance with GDPR (data protection) and HIPAA (health data privacy) if sensitive data is exposed.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the memory corruption vulnerability in Fonts.
