AI-suggested
- Immediate update to Google Chrome version 145.0.7632.159 or later to apply the patch addressing this vulnerability.
- Employ network-level protections such as web filtering and intrusion prevention systems to block access to known malicious sites hosting crafted WebAssembly content.
- Enable browser security features like site isolation and sandboxing to limit the impact of potential exploitation.
- Monitor browser crash reports and unusual WebAssembly activity for signs of attempted exploitation.
- Educate users on safe browsing practices to reduce the risk of visiting untrusted or suspicious websites.
- For enterprise environments, consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation attempts targeting browser memory corruption.
- Maintain an up-to-date inventory of browser versions in use across the organization to ensure timely patch management.
- Limit or control the use of WebAssembly in browsers via policy or extensions where feasible, especially in high-security environments. These measures collectively reduce the risk of exploitation and limit potential damage if an attack occurs.
Description
Inappropriate implementation in WebAssembly in Google Chrome prior to 145.0.7632.159 allowed a remote attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity: High)
