Webpack version 0.4.2 represents a marginal update from its predecessor, version 0.4.1, both iterations designed to bundle CommonJs modules for streamlined browser deployment. The core functionality remains consistent: enabling developers to split their codebase into manageable chunks for on-demand loading, enhancing initial load times and overall user experience. Both versions boast out-of-the-box support for various file types including JavaScript, JSON, Jade, CoffeeScript, and CSS. This eliminates the need for extensive configuration when working with common web development technologies. The dependency lists are identical, encompassing essential packages like esprima for JavaScript parsing, sprintf for string formatting, optimist for command-line argument parsing, and uglify-js for code minification. A suite of loaders (css-loader, raw-loader, val-loader, file-loader, jade-loader, json-loader, less-loader, style-loader, bundle-loader, coffee-loader, script-loader) provides immediate support for processing different file types. While the feature set is virtually unchanged, the primary distinction lies in the release date, with version 0.4.2 released three days later and including potentially minor fixes or very small updates under the hood. Both depend on older versions of their dependencies, so, due to the rapid evolution of tooling in the JavaScript ecosystem, developers should consider upgrading to current versions of Webpack to access newer features and security updates.
All the vulnerabilities related to the version 0.4.2 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.
