Language: JavaScript

Severity: Warning

Category: Security


Dealing with binary data can be achieved with the Node.js Buffer class. However, if you use non-literal params, this could lead to malicious control over the value, resulting in an attack.

For example, a large number could allocate a significant amount of memory leading to a denial of service attack. It is recommended to use literal values that you can control to prevent these attacks.

Non-Compliant Code Examples

var a = new Buffer(c)

Compliant Code Examples

var a = new Buffer('test')
