openssl 1.0.2h vulnerabilities
What to do
Partial vendor fix. Follow the primary source's mitigation guidance and check back for a fix.
This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description
As published by the source; long descriptions are shortened.
Some missing message length checks can result in out of bounds (OOB) reads of up to 2 bytes beyond an allocated buffer. There is a theoretical denial of service (DoS) risk. This only impacts a client or a server which enables client authentication. Node.js is impacted by this low severity flaw.

# Patch Next advisory brief: CVE-2016-6306 Advisory: openssl 1.0.2h vulnerabilities IDs: CVE-2016-6306 Record: https://patchnext.com/advisories/cve-2016-6306 (revision 2, source checked 26 Oct 2026, 16:35 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Unrated Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Partial vendor fix; fixed versions by package: node 6.7.0, 4.6.0. A vendor fix does not mean a deployment is fixed. ## Affected components - runtime node: affected >= 6.0.0, < 6.7.0; >= 5.0.0, < 6.0.0; >= 4.0.0, < 4.6.0; fixed in 6.7.0, 4.6.0 ## Suggested inspection (read-only) - runtime node: check the installed version with your package manager. ## Supported action No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on node. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://raw.githubusercontent.com/nodejs/security-wg/main/vuln/core/16.json (Node.js security working group core entry 16 lists CVE-2016-6306 affecting node >=6.0.0 =5.0.0 =4.0.0 <4.6.0) - Verified: https://nodejs.org/dist/index.json (The nodejs.org release index dates the first patched release for CVE-2016-6306 to 2016-09-27.)
