Descriptions

An out-of-bounds read/write vulnerability when executing lazily compiled inner generator functions in Facebook Hermes prior to commit 091835377369c8fd5917d9b87acffa721ad2a168 allows attackers to potentially execute arbitrary code 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 vulnerabilidad de lectura/escritura fuera de límites cuando se ejecutan funciones inner generator compiladas perezosamente en Facebook Hermes anterior del commit 091835377369c8fd5917d9b87acffa721ad2a168, permite a atacantes ejecutar potencialmente código arbitrario por medio de un JavaScript diseñado. Tome en cuenta que esto solo es explotable si la aplicación que utiliza Hermes permite la evaluación de JavaScript que no es de confianza. Por lo tanto, la mayoría de las aplicaciones React Native no están afectadas.
