Denial of Service (DoS)

hermes-engine is an A JavaScript engine optimized for running React Native on Android

Affected versions of this package are vulnerable to Denial of Service (DoS) by passing invalid JavaScript code where await and yield were called upon non-async and non-generator getter/setter functions. In this case, Hermes would invoke generator functions and error out on invalid await/yield positions. This could result in segmentation fault as a consequence of type confusion error, with a low chance of RCE.

How to fix Denial of Service (DoS)?

Upgrade hermes-engine to version 0.10.0 or higher.

<0.10.0
