CVE-2017-3736 Open this link in a new tabHow to fix?
Upgrade OpenSSL
to version 1.0.211 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 Information Exposure. OpenSSL is vulnerable to a carry propagation issue with the x86_64 Montgomery squaring procedure. This attack can be carried out against unpatched systems using a target private key with persistent DH parameters and a private key which is shared with multiple clients. This could in some circumstances lead to information disclosure as it makes it easier to deduce information about the private key.
This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen.
