A use-after-free in BigIntPrimitive addition in Hermes prior to commit a6dcafe6ded8e61658b40f5699878cd19a481f80 could have been used by an attacker to leak raw data from Hermes VM’s heap. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.

A bytecode optimization bug in Hermes prior to commit e6ed9c1a4b02dc219de1648f44cd808a56171b81 could be used to cause an use-after-free and obtain arbitrary code execution via a carefully crafted payload. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.

A use-after-free related to unsound inference in the bytecode generation when optimizations are enabled for Hermes prior to commit da8990f737ebb9d9810633502f65ed462b819c09 could have been used by an attacker to achieve remote code execution. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.

HHVM 4.172.0 and all prior versions use TLS 1.0 for secure connections when handling tls:// URLs in the stream extension. TLS1.0 has numerous published vulnerabilities and is deprecated. HHVM 4.153.4, 4.168.2, 4.169.2, 4.170.2, 4.171.1, 4.172.1, 4.173.0 replaces TLS1.0 with TLS1.3.
Applications that call stream_socket_server or stream_socket_client functions with a URL starting with tls:// are affected.

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.
