Access of Resource Using Incompatible Type in Hermes
Packages

| npm | hermes-engine | < 0.10.0 | 0.10.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
By passing invalid javascript code where await and yield were called upon non-async and non-generator getter/setter functions, 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. This issue affects Hermes versions prior to v0.10.0.
