What is CVE-2018-16395?

A flaw was identified in the OpenSSL library used by Ruby, where two OpenSSL::X509::Name objects can be incorrectly evaluated as equal under certain conditions. This occurs if the objects have characters that differ by one position or length. Consequently, it can lead to the creation of illegitimate certificates, which may be erroneously trusted, posing risks for signing and encryption operations.
