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 Out-of-Bounds. OpenSSL is vulnerable to denial of service (DoS) attacks and possibly other attacks. These attacks are possible because of an integer underflow in the EVP_DecodeUpdate function. The use of base64 data can trigger this buffer overflow which can cause memory corruption.
