How to fix?

Upgrade OpenSSL to version 1.0.207, 1.0.207 or higher.

Overview

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 to Denial of Service (DoS) attacks. The doapr_outch function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g, found in the affected versions of OpenSSL, does not verify that certain memory allocations succeed, allowing a malicious user to cause a denial of service by passing a large string to the server, crashing it due to the server running out of memory.
