Webpack version 0.11.16 is a minor update to the popular module bundler, following closely on the heels of version 0.11.15. Both versions serve the core purpose of packing CommonJs, AMD, and labeled modules for browser deployment, allowing developers to split codebases into manageable bundles that can be loaded on demand. This functionality is crucial for optimizing website performance and user experience. The key feature remains the support for loaders, which preprocess various file types like JSON, Jade, CoffeeScript, CSS, and LESS, offering developers a flexible and customizable build process.
The dependencies and devDependencies sections for both versions are identical, indicating that the core functionality and the tools used for development and testing remain consistent. This suggests that the changes between 0.11.15 and 0.11.16 are likely bug fixes, performance improvements, or minor enhancements rather than significant feature additions. Developers upgrading from 0.11.15 to 0.11.16 can expect a seamless transition with no breaking changes to the API or configuration. The release date difference indicates a rapid iteration cycle, signifying ongoing maintenance and refinement of the webpack tool. While the core functionality remains unchanged, upgrading is generally recommended to benefit from any potential bug fixes and performance enhancements included in the newer version.
All the vulnerabilities related to the version 0.11.16 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;");
