How to fix?

Upgrade OpenSSL to version 1.0.200, 1.0.209 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 Out-of-bounds Write. OpenSSL is vulnerable to denial of service (DoS) attacks. The library does not validate division results, allowing a malicious user to cause a denial of service via an out-of-bounds write by sending a overly large BIGNUM.
