## Vendor fix

Update to the latest wolfSSL version, apply the fix patch, or disable OpenSSL compatible defaults and avoid loading CA certificates with wolfSSL\_CTX\_trust\_peer\_cert() or wolfSSL\_trust\_peer\_cert().

Patching closes this CVE. It does not tell you which of your systems run the affected version, or what else is exposed alongside them.
