How to fix?

Upgrade OpenSSL to version 1.0.201 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 Code. OpenSSL is vulnerable to denial of service (DoS) attacks. These attacks are possible because OpenSSL does not reinitialize the CHOICE and ADB data structures, allowing attackers to cause invalid write operations and memory corruption through an application that relies on ASN.1 structure reuse.
