Webpack version 0.4.16 is a minor update to the popular module bundler, succeeding version 0.4.15. Both versions share the same core functionality of packing CommonJs modules for browser use, enabling code splitting into multiple bundles loaded on demand. This allows for optimized website performance by only loading necessary code when required. The tool supports various file types out of the box, including JavaScript, JSON, Jade, CoffeeScript, and CSS, and can be extended to support others using custom loaders.
The dependency list remains consistent between the two versions, including crucial libraries like esprima for JavaScript parsing, sprintf for string formatting, optimist for command-line argument parsing, and uglify-js for code minification. Loaders for CSS, raw files, value extraction, files, Jade templates, JSON, LESS stylesheets, embedded styles, bundles, CoffeeScript, and general scripts are also unchanged, ensuring compatibility with existing configurations. The devDependencies for testing (mocha and should) are also the same.
The primary difference is the release date. Version 0.4.16 was released on July 11, 2012, shortly after version 0.4.15 which was released on July 10, 2012. This suggests that version 0.4.16 likely contains bug fixes or minor improvements over its predecessor. While specific details on the changes between the releases might be found in the changelog or commit history, users upgrading from version 0.4.15 can expect similar functionality. Given the minimal time separating their releases, upgrading to 0.4.16 is recommended for potential bug fixes, while offering the same powerful module bundling capabilities.
All the vulnerabilities related to the version 0.4.16 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.
