Red Hat
Red Hat rates this Important.
This vulnerability is rated as Important severity rather than Critical because exploitation requires prior compromise of the renderer process as well as user interaction to navigate to a malicious web page. In Red Hat Enterprise Linux desktop environments where the browser is utilized to access external web content, an adversary could leverage this memory boundary violation in the graphics subsystem to exfiltrate sensitive data across the sandbox isolation barrier. The impact is primarily restricted to unauthorized information disclosure from outside the sandbox rather than immediate arbitrary code execution.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
