Descriptions

An Integer signedness error in the JavaScript Interpreter in Facebook Hermes prior to commit 2c7af7ec481ceffd0d14ce2d7c045e475fd71dc6 allows attackers to cause a denial of service attack or a potential RCE 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.

Un error en la propiedad signedness de Enteros en el intérprete de JavaScript en Facebook Hermes anterior al commit 2c7af7ec481ceffd0d14ce2d7c045e475fd71dc6, permite a atacantes causar un ataque de denegación de servicio o una potencial RCE por medio de un JavaScript diseñado. Tome en cuenta que esto solo es explotable si la aplicación que utiliza Hermes permite la evaluación del JavaScript que no es de confianza. Por lo tanto, la mayoría de las aplicaciones React Native no están afectadas.
