Frequently Asked Questions
1
Is visiting a crafted HTML page alone sufficient to exploit this issue?
The available information says the attacker must already have compromised the renderer process. A crafted HTML page is then used to potentially execute code outside the browser sandbox.
2
What is the security impact if the required conditions are met?
A successful exploit could allow arbitrary code execution outside Chrome's sandbox. The reported impact includes high confidentiality, integrity, and availability consequences.
