Descriptions

An out-of-bounds read in the JavaScript Interpreter in Facebook Hermes prior to commit 8cb935cd3b2321c46aa6b7ed8454d95c75a7fca0 allows attackers to cause a denial of service attack or possible further memory corruption via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.

Una lectura fuera de límites en el intérprete de JavaScript en Facebook Hermes anterior al commit 8cb935cd3b2321c46aa6b7ed8454d95c75a7fca0, permite a atacantes causar un ataque de denegación de servicio o una posible corrupción adicional de la memoria por medio de un JavaScript diseñado. Tome en cuenta que esto solo puede ser aprovechado si la aplicación que usa Hermes permite la evaluación de un JavaScript que no es confiable. Por consiguiente, la mayoría de las aplicaciones React Native no están afectadas
