Webpack version 0.3.9 presents a minor update over its predecessor, version 0.3.8, both aiming to streamline CommonJs module bundling for browser deployment. These early iterations of Webpack are designed to empower developers with the ability to divide codebases into manageable bundles, optimizing loading times and enhancing the user experience through on-demand loading.
The core functionality remains consistent: out-of-the-box support for prevalent file types like JavaScript, JSON, Jade, CoffeeScript, and CSS, further extensible through custom loaders. This allows developers to seamlessly integrate various assets into their projects. The dependency structure is identical, featuring essential tools such as esprima for JavaScript parsing, sprintf for string formatting, optimist for command-line argument parsing, and uglify-js for code minification. They also incorporate loaders for common web resources: CSS, raw text, Jade templates, JSON data, LESS stylesheets, styling purposes, CoffeeScript files, and external scripts.
The key distinguishing factor between versions 0.3.8 and 0.3.9 lies in their release dates. Version 0.3.9 was published a few hours later than 0.3.8, suggesting that this subsequent release likely addresses minor bug fixes, dependency updates, or other slight adjustments not explicitly detailed in the package metadata. For developers, upgrading ensures accessing the most current and potentially refined version of the tool, mitigating potential issues and enhancing overall build process stability. While not a feature-rich upgrade, staying current is generally recommended for optimal performance.
All the vulnerabilities related to the version 0.3.9 of the package
Incorrect Handling of Non-Boolean Comparisons During Minification in uglify-js
Versions of uglify-js prior to 2.4.24 are affected by a vulnerability which may cause crafted JavaScript to have altered functionality after minification.
Upgrade UglifyJS to version >= 2.4.24.
Regular Expression Denial of Service in uglify-js
Versions of uglify-js prior to 2.6.0 are affected by a regular expression denial of service vulnerability when malicious inputs are passed into the parse() method.
var u = require('uglify-js');
var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");

Update to version 2.6.0 or later.
Regular Expression Denial of Service in clean-css
Version of clean-css prior to 4.1.11 are vulnerable to Regular Expression Denial of Service (ReDoS). Untrusted input may cause catastrophic backtracking while matching regular expressions. This can cause the application to be unresponsive leading to Denial of Service.
Upgrade to version 4.1.11 or higher.
Sandbox Bypass Leading to Arbitrary Code Execution in constantinople
Versions of constantinople prior to 3.1.1 are vulnerable to a sandbox bypass which can lead to arbitrary code execution.
Update to version 3.1.1 or later.
