Detailed vulnerability description
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in the remote media URL handling feature when processing remote media URLs. A remote user can supply a slow-reading remote media URL to cause a denial of service.
Only instances where the affected feature is enabled and reachable are vulnerable, and practical impact depends on whether lower-trust input can reach that path.
