What is CVE-2016-7798?

The OpenSSL gem for Ruby exhibits a vulnerability where it uses the same initialization vector (IV) in GCM Mode when the IV is set prior to the encryption key. This flaw permits context-dependent attackers to exploit the IV reuse, potentially compromising the integrity of the encryption protocol and allowing them to bypass security measures in scenarios where encryption is a critical component of data protection.
