CWE-843  (opens in a new tab)

How to fix?

Upgrade OpenSSL-Universal to version 1.1.2000 or higher.

Overview

OpenSSL-Universal is a complete solution to OpenSSL on iOS and OSX

Affected versions of this package are vulnerable to Access of Resource Using Incompatible Type ('Type Confusion') in x509/v3_genn.c, when processing X.400 addresses with CRL checking enabled (e.g. when X509_V_FLAG_CRL_CHECK is set). An attacker in possession of both the certificate chain and CRL, of which neither needs a valid signature, can expose memory or cause a denial of service. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon.
