Multiple unspecified vulnerabilities in Google V8 before 3.23.17.18, as used in Google Chrome before 33.0.1750.149, allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

Use-after-free vulnerability in the WebSocketDispatcherHost::SendOrDrop function in content/browser/renderer_host/websocket_dispatcher_host.cc in the Web Sockets implementation in Google Chrome before 33.0.1750.149 might allow remote attackers to bypass the sandbox protection mechanism by leveraging an incorrect deletion in a certain failure case.

Use-after-free vulnerability in modules/speech/SpeechSynthesis.cpp in Blink, as used in Google Chrome before 33.0.1750.149, allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging improper handling of a certain utterance data structure.

Use-after-free vulnerability in the DatabaseThread::cleanupDatabaseThread function in modules/webdatabase/DatabaseThread.cpp in the web database implementation in Blink, as used in Google Chrome before 33.0.1750.149, allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging improper handling of scheduled tasks during shutdown of a thread.

The GenerateFunction function in bindings/scripts/code_generator_v8.pm in Blink, as used in Google Chrome before 33.0.1750.149, does not implement a certain cross-origin restriction for the EventTarget::dispatchEvent function, which allows remote attackers to conduct Universal XSS (UXSS) attacks via vectors involving events.
