Extensions Lazy Event Dispatcher

This page analyzes the security of the lazy event dispatcher for extensions.

Component Focus

extensions/browser/events/lazy_event_dispatcher.cc and related files.

Potential Logic Flaws

• The file manages the dispatch of events to lazy contexts, which could be a potential attack vector if not implemented securely.
• The file handles event queueing, which could be vulnerable to queue-related issues.
• The file interacts with the extension system, which could be vulnerable to extension-related issues.
• The file uses callbacks, which could be vulnerable to callback-related issues.

Further Analysis and Potential Issues

• The LazyEventDispatcher class manages the dispatch of events to lazy contexts. This class should be carefully analyzed for potential vulnerabilities, such as improper initialization or resource leaks.
• The file uses a queue to manage pending events. This queue should be carefully analyzed for potential vulnerabilities, such as queue overflow or race conditions.
• The file interacts with the extension system to determine if an extension is ready to receive events. This interaction should be carefully analyzed for potential vulnerabilities, such as permission bypasses or unauthorized access.
• The file uses callbacks to dispatch events. These callbacks should be carefully analyzed for potential vulnerabilities, such as use-after-free or double-free issues.
• The file uses base::BindOnce to bind callbacks. This should be analyzed for potential issues with the bound callbacks.

Areas Requiring Further Investigation

• How are events routed to the correct lazy context?
• What are the security implications of a malicious extension manipulating the event queue?
• How does the lazy event dispatcher handle errors during event dispatch?
• How does the lazy event dispatcher interact with the extension system?
• What are the performance implications of lazy event dispatch?

Secure Contexts and Extensions Lazy Event Dispatcher

• How do secure contexts interact with the lazy event dispatcher?
• Are there any vulnerabilities related to secure contexts and the lazy event dispatcher?

Privacy Implications

• What are the privacy implications of lazy event dispatch?
• Could a malicious extension use the lazy event dispatcher to track users?

Additional Notes

• This component is part of the extensions module.
• This component interacts with the extension system and the event router.
