Browserify, a vital tool for JavaScript developers, allows the use of Node.js-style require() in browser-based projects, streamlining front-end development. Version 3.20.0, released on January 13, 2014, builds upon the solid foundation of its predecessor, version 3.19.1, launched just a week prior on January 6, 2014. A close examination reveals that the core dependencies remain consistent between the two releases, suggesting that the update from 3.19.1 to 3.20.0 likely includes bug fixes, minor enhancements, or optimizations that don't necessitate dependency changes. Key dependencies like umd, url, util, assert, and many others crucial for emulating the Node.js environment within a browser, stay at the same versions. This stability indicates a focus on refining existing functionality rather than introducing significant new features in this particular update.
Developers should note that both versions share the same development dependencies, including tools for testing (tap), debugging (dnode), and build processes (mkdirp, coffee-script). This signals a commitment to quality and a robust development workflow. While the specific changes from 3.19.1 to 3.20.0 aren't explicitly detailed in the provided data, the consistent dependency list suggests a relatively minor update focused on stability and efficiency. For projects already using Browserify, upgrading to 3.20.0 is likely a safe and recommended step, potentially offering improved performance or addressing subtle issues. Developers are encouraged to consult the changelog or commit history for a complete list of changes.
All the vulnerabilities related to the version 3.20.0 of the package
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;");

$ time node test.js 80000
real 0m6.486s

Update to version 2.6.0 or later.
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).
Potential Command Injection in shell-quote
Affected versions of shell-quote do not properly escape command line arguments, which may result in command injection if the library is used to escape user input destined for use as command line arguments.
The following characters are not escaped properly: >,;,{,}
Bash has a neat but not well known feature known as "Bash Brace Expansion", wherein a sub-command can be executed without spaces by running it between a set of {} and using the , instead of to seperate arguments. Because of this, full command injection is possible even though it was initially thought to be impossible.
const quote = require('shell-quote').quote;
console.log(quote(['a;{echo,test,123,234}']));
// Actual "a;{echo,test,123,234}"
// Expected "a\;\{echo,test,123,234\}"
// Functional Equivalent "a; echo 'test' '123' '1234'"
Update to version 1.6.1 or later.
Potential for Script Injection in syntax-error
Versions of syntax-error prior to 1.1.1 are affected by a cross-site scripting vulnerability which may allow a malicious file to execute code when browserified.
Update to version 1.1.1 or later.
