Summary
Our tool detected a potential vulnerability in ThirdParty/LibreSSL/crypto/x509/x509_utl.c which was cloned from openssl/openssl but did not receive the security patch applied. The original issue was reported and fixed under https://nvd.nist.gov/vuln/detail/cve-2021-3712.
Proposed Fix
Apply the same patch as the one in openssl/openssl to eliminate the vulnerability.
