CVE-2023-23557
https://notcve.org/view.php?id=CVE-2023-23557
An error in Hermes' algorithm for copying objects properties prior to commit a00d237346894c6067a594983be6634f4168c9ad could be used by a malicious attacker to execute arbitrary code via type confusion. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected. • https://github.com/facebook/hermes/commit/a00d237346894c6067a594983be6634f4168c9ad https://www.facebook.com/security/advisories/cve-2023-23557 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

https://notcve.org/view.php?id=CVE-2023-23556
An error in BigInt conversion to Number in Hermes prior to commit a6dcafe6ded8e61658b40f5699878cd19a481f80 could have been used by a malicious attacker to execute arbitrary code due to an out-of-bound write. Note that this bug is only exploitable in cases where Hermes is used to execute untrusted JavaScript.

CVE-2022-35289
https://notcve.org/view.php?id=CVE-2022-35289
A write-what-where condition in hermes caused by an integer overflow, prior to commit 5b6255ae049fa4641791e47fad994e8e8c4da374 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 condición write-what-where en Hermes causada por un desbordamiento de enteros, versiones anteriores al commit 5b6255ae049fa4641791e47fad994e8e8c4da374 permite a atacantes ejecutar potencialmente código arbitrario por medio de JavaScript diseñado. Tenga en cuenta que esto sólo es explotable si la aplicación que usa Hermes permite la evaluación de JavaScript no confiable. • https://github.com/facebook/hermes/commit/5b6255ae049fa4641791e47fad994e8e8c4da374 https://www.facebook.com/security/advisories/CVE-2022-35289 • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
CVE-2022-32234
https://notcve.org/view.php?id=CVE-2022-32234
An out of bounds write in hermes, while handling large arrays, prior to commit 06eaec767e376bfdb883d912cb15e987ddf2bda1 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 escritura fuera de límites en Hermes, mientras son manejados arrays grandes, antes del commit 06eaec767e376bfdb883d912cb15e987ddf2bda1 permite a atacantes ejecutar potencialmente código arbitrario por medio de JavaScript diseñado. Tenga en cuenta que esto sólo es explotable si la aplicación que usa Hermes permite la evaluación de JavaScript no confiable. • https://github.com/facebook/hermes/commit/06eaec767e376bfdb883d912cb15e987ddf2bda1 https://www.facebook.com/security/advisories/CVE-2022-32234 • CWE-787: Out-of-bounds Write •
CVE-2022-40138
https://notcve.org/view.php?id=CVE-2022-40138
An integer conversion error in Hermes bytecode generation, prior to commit 6aa825e480d48127b480b08d13adf70033237097, could have been used to perform Out-Of-Bounds operations and subsequently execute arbitrary code. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected. Un error de conversión de enteros en la generación de bytecode de Hermes, anterior al commit 6aa825e480d48127b480b08d13adf70033237097, podría haber sido usado para llevar a cabo operaciones Fuera de Límites y posteriormente ejecutar código arbitrario. Tenga en cuenta que esto sólo es explotable en los casos en que Hermes es usado para ejecutar JavaScript no confiable. • https://github.com/facebook/hermes/commit/6aa825e480d48127b480b08d13adf70033237097 https://www.facebook.com/security/advisories/CVE-2022-40138 • CWE-681: Incorrect Conversion between Numeric Types •
