Red Hat
Red Hat rates this Important.
This vulnerability is rated as Important because an unauthenticated remote attacker could execute arbitrary code within the renderer process if a user is enticed to open malicious web content. In Red Hat Enterprise Linux environments, chromium-browser is an optional graphical package used for interactive desktop sessions rather than standard server workloads. Although the flaw allows memory corruption during frame handling, damage is restricted to the browser sandbox environment, which prevents direct operating system takeover without an accompanying privilege escalation or sandbox bypass.
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.
