+## Summary
+
+The vulnerability in the OpenSSL Security release of Oct 11 2022 does not affect any active Node.js release lines, as well
+as the zlib vulnerability ([CVE-2022-37434][]) patched on the zlib Security release of Oct 13 2022, does not affect Node.js.
+
+## Analysis OpenSSL
+
+Our assessment of the [security advisory](https://mta.openssl.org/pipermail/openssl-announce/2022-October/000236.html) is:
+
+### Using a Custom Cipher with `NID_undef` may lead to NULL encryption (CVE-2022-3358)
+
+Node.js doesn't call `EVP_CIPHER_meth_new(NID_undef, ...)`. Therefore, Node.js is not affected by this vulnerability.
+
+## Analysis zlib
+
+Our assessment of the [CVE-2022-37434][] is:
+
+### Buffer overflow in inflate via a large gzip header extra field
+
+Node.js doesn't call `inflateGetHeader`. Therefore, Node.js is not affected by this vulnerability.
+
+Further information, see: [nodejs-dependency-vuln-assessments#50][].
+
+## Node.js Vulnerability Assessment workflow
+
+The Node.js Security team created an automated workflow that aims to address all the public CVE of Node.js dependencies.
+
+This initiative aims to reduce the gap between a dependency security release and a Node.js assessment.
+The repository is available at [nodejs/nodejs-dependency-vuln-assessments][], and the assessments are made through the
+issues.
+
+Ensure to watch the repository if you are interested in security patches.
+
+### Contact and future updates
+
+The current Node.js security policy can be found at <https://github.com/nodejs/node/blob/HEAD/SECURITY.md#security>,
+including information on how to report a vulnerability in Node.js.
+
+Subscribe to the low-volume announcement-only **nodejs-sec** mailing list at
+https://groups.google.com/forum/#!forum/nodejs-sec to stay up to date on
+security vulnerabilities and security-related releases of Node.js and the
+projects maintained in the
+[Node.js GitHub organization][].
