CVE-2020-1913 (GCVE-0-2020-1913)

Vulnerability from cvelistv5 – Published: 2020-09-09 19:00 – Updated: 2024-08-04 06:53
VLAI
Summary
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.
