Description Patrick Del Bello 2022-10-07 12:06:58 UTC
It was possible to trigger an infinite recursion condition in the error handler when Hermes executed specific maliciously formed JavaScript. This condition was only possible to trigger in dev-mode (when asserts were enabled). This issue affects Hermes versions prior to v0.12.0.
