Webpack version 0.3.18 represents a minor update over its preceding stable release, version 0.3.17, focusing on potential bug fixes and incremental improvements rather than groundbreaking feature additions. Examining the package metadata reveals minimal changes beyond the version number and associated release date. Both versions share the same core functionality: packing CommonJs modules for browsers, enabling code splitting for on-demand loading, and offering built-in support for various asset types like JavaScript, JSON, Jade, CoffeeScript, and CSS, expandable with custom loaders. The dependency list remains identical, encompassing essential tools like esprima, sprintf, optimist, uglify-js, and 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). Developers relying on webpack during this era (mid-May 2012) would find that upgrading from 0.3.17 to 0.3.18 likely provides a more stable experience with potential resolutions to edge-case issues encountered in the prior version. While the core feature set remains consistent, the newer version offers a refined and potentially more dependable tool for managing and optimizing browser-based JavaScript applications. The development dependencies, indicated by "vows": "*", suggest similar testing and quality assurance processes were utilized across both releases.
All the vulnerabilities related to the version 0.3.18 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.
