How to fix?

Upgrade OpenSSL to version 1.0.109, 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 via timing (side-channel) attacks. The vulnerability exists due to the lack of constant time comparison during the RSA key generation of p and q, resulting in the potential ability to recover the private key.
