Descriptions

An asynchronous generator may return an incorrect state in V8 in Google Chrome prior to 66.0.3359.117 allowing a remote attacker to potentially exploit object corruption via a crafted HTML page.

Un generador asíncrono podría devolver un estado incorrecto en V8 en Google Chrome, en versiones anteriores a la 66.0.3359.117, lo que permite que un atacante remoto explote una corrupción de objetos mediante una página HTML manipulada.

Google Chrome V8 Await methods call ResolveNativePromise which calls InternalResolvePromise which can invoke a user JavaScript code through a "then" getter. If the AwaitedPromise is replaced by the user script, the AwaitedPromise will be immediately overwritten after the call to Await, this may lead the generator to an incorrect state.
