Insecure Buffer Allocation
Description
The application uses the deprecated `new Buffer` constructor, which can lead to memory allocation issues and potential security vulnerabilities. Older versions of Node.js may return uninitialized memory, potentially exposing sensitive information. To remediate this issue, use `Buffer.alloc` or `Buffer.from` instead to allocate a new `Buffer`.
Examples
Insecure Code
javascript
const buf = new Buffer([1, 2, 3, 4]);Secure Code
javascript
const buf = Buffer.from([1, 2, 3, 4]);Remediation
Replace `new Buffer` with `Buffer.alloc` or `Buffer.from`
