Red Hat
Red Hat rates this Important.
This vulnerability is rated as an Important severity flaw because an unauthenticated remote attacker can trigger memory corruption leading to code execution within the renderer process by tricking a user into rendering malicious web content. While execution is typically restricted by the browser's multi-process sandbox, compromise of the rendering engine allows unauthorized access to sensitive browsing session data and provides an initial foothold. Red Hat Enterprise Linux systems deploying Chromium as a desktop browser are susceptible when users navigate to untrusted websites.
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.
