What is CVE-2024-34447?

A DNS poisoning vulnerability was identified in Bouncy Castle Java Cryptography APIs prior to version 1.78. When endpoint identification is active, an SSL socket may be initialized without an explicit hostname. This can lead to hostname verification checks against a DNS-resolved IP address, creating a risk for potential exploitation through malicious DNS responses. It's essential for developers and system administrators to be aware of this flaw and ensure they are using an updated version of the software to mitigate risks.
