CVE-2017-6076 Wolfssl CVE debrief

Who should care

Administrators and product teams using wolfSSL, especially in shared systems, appliances, embedded devices, or any environment where local users may have access to system caches or adjacent runtime data.

Technical summary

NVD classifies the issue as CVSS 3.0 5.5/Medium with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N and CWE-200. The vulnerable CPE range covers wolfssl:wolfssl versions earlier than 3.10.2. The described impact is confidentiality-only exposure of RSA key information, and the vendor release reference points to 3.10.2 as the patch boundary.

Defensive priority

Medium priority. Treat as higher priority on multi-user hosts, shared appliances, or deployments where local privilege boundaries are important and caches may be accessible to untrusted users.

Recommended defensive actions

• Upgrade wolfSSL to version 3.10.2 or later.
• Inventory products and firmware that bundle wolfSSL and verify the embedded library version.
• Restrict local user access and any ability to inspect process or system cache data on affected hosts.
• Review vendor release notes and dependency update paths before redeploying affected systems.
• If immediate upgrade is not possible, isolate affected systems and reduce local access exposure until patched.

Evidence notes

This debrief is grounded in the CVE description, the NVD record, and the wolfSSL 3.10.2 stable release reference. The NVD metadata lists wolfssl:wolfssl versions end-excluding 3.10.2 as vulnerable and assigns CWE-200. No CISA KEV entry was provided in the supplied corpus.
