How to fix?

There is no fixed version for OpenSSL.


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 Buffer Overflow. Openssl assumed ASN.1 strings to be NUL terminated. A malicious actor may be able to force an application into calling openssl function with a specially crafted, non-NUL terminated string to deliberately hit this bug, which may result in a crash of the application, causing a Denial of Service attack, or possibly, memory disclosure.
