Descriptions

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.

Al pasar código javascript no válido en el que era llamado a await y yield sobre funciones getter/setter no asíncronas y no generadoras, Hermes invocaba funciones generadoras y daba error en posiciones await/yield no válidas. Esto podría resultar en un fallo de segmentación como consecuencia de un error de confusión de tipos, con una baja probabilidad de RCE. Este problema afecta a Hermes versiones anteriores a v0.10.0
