How to fix?

Upgrade OpenSSL to version 1.0.205 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 Information Exposure. OpenSSL is vulnerable to information disclosure. The library contains a carry propagation bug during the montgomery squaring procedure. This makes it easier for a malicious user to obtain sensitive private key information from the Diffie-Hellman and Diffie-Hellman Ephemereal Ciphersuites.
