How to fix?

Upgrade OpenSSL to version 1.0.109 or higher.

Overview

OpenSSL is a SSL/TLS and Crypto toolkit. Deprecated in Mac OS and gone in iOS, this spec gives your project non-deprecated OpenSSL support.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). OpenSSL is vulnerable to man in the middle (MitM) attacks. These attacks are possible through the ssl23_get_client_hello function in s23_srvr.c. It can be triggered by a ClientHello message fragment which forces OpenSSL to negotiate using the TLS 1.0 protocol insteadl of a higher, more secure version.
