How to fix?

Upgrade OpenSSL to version 1.0.108 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 protection mechanism bypass. This is because OpenSSL accepts several variations of certificate signature algorithms and signature encodings. It doesn't then enforce a match between the signature algorithm between the signed and unsigned portions of the certificate. This only affects custom applications which rely on the uniqueness of the fingerprint.
