What is CVE-2020-9434?

The lua-openssl library versions prior to 0.7.7-1 experience a flaw in the openssl_x509_check_ip_asc function, which mishandles X.509 certificate validation. This occurs due to the improper use of lua_pushboolean, leading to certain non-boolean return values being misinterpreted. Consequently, this can result in potential security issues, as the integrity of certificate verification may be compromised.
