+## Analysis
+
+Our assessment of the following security advisories:
+
+- [OpenSSL 3.0.11](https://mta.openssl.org/pipermail/openssl-announce/2023-September/000273.html)
+- [OpenSSL 3.0.12](https://mta.openssl.org/pipermail/openssl-announce/2023-October/000282.html)
+
+is:
+
+### POLY1305 MAC implementation corrupts XMM registers on Windows (CVE-2023-4807) - Low
+
+Node.js is affected by this vulnerability. The CVE-2023-4807
+affects Windows users, and the vulnerability is rated as LOW by the OpenSSL
+Security Team.
+
+### Incorrect cipher key & IV length processing (CVE-2023-5363) - Moderate
+
+Node.js doesn't make use or export `EVP_EncryptInit_ex2()`, `EVP_DecryptInit_ex2()` or
+`EVP_CipherInit_ex2()` functions. Node.js is not affected.
+
+Users who call the affected OpenSSL functions through other means,
+such as through native addons, can dynamically link against a patched version of OpenSSL
+until new releases of Node.js are available.
+
