How to fix?

Upgrade OpenSSL to version 1.0.206 or higher.


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 Cryptographic Issues. OpenSSL is vulnerable to cipher bypasses. A malicious user can negotiate and complete an SSLv2 handshake with the server even if the ciphers have been disabled on the server. SSLv2 handshakes are vulnerable to man-in-the-middle attacks.
