How to fix?

There is no fixed version for openssl.

Overview

openssl is a package that wraps the OpenSSL library.

Affected versions of this package are vulnerable to NULL Pointer Dereference when processing a maliciously formatted PKCS12 file. The vulnerability exists due to improper handling of optional ContentInfo fields, which can be set to null. An attacker can cause a denial of service by sending crafted input that leads to applications loading files in PKCS12 format from untrusted sources to terminate abruptly.
