+### Summary
+
+The OpenSSL Security releases of September 10th, 2019 do not affect Node.js.
+
+### Analysis
+
+Our assessment of the [security advisory](https://www.openssl.org/news/secadv/20190910.txt) is:
+
+- ECDSA remote timing attack (CVE-2019-1547)
+  Not affected. Node supports only named curves for ECDSA signing.
+
+- Fork Protection (CVE-2019-1549)
+  Not affected. Node.js always call `exec()` after `fork()` so will not the
+  duplicate PRNG state in the forked process.
+
+- Padding Oracle in `PKCS7_dataDecode` and `CMS_decrypt_set1_pkey` (CVE-2019-1563)
+  Not affected. Node does not support PCKS7 and CMS.
+
+Given this assessment, the OpenSSL updates will be treated as non-security
+patch updates, and will come out in the regularly scheduled updates to
+supported release lines.
