Summary

Our tool detected a potential vulnerability in 3rdparty/openssl/crypto/asn1/tasn_enc.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-2020-1971.

Proposed Fix

Apply the same patch as the one in openssl/openssl to eliminate the vulnerability.

Reference

openssl/openssl@3db2c9f

It never makes sense for multi-string or CHOICE types to have implicit
tagging. If we have a template that uses the in this way then we
should immediately fail.

Thanks to David Benjamin from Google for reporting this issue.
