Browserify version 2.4.3 represents a minor update to the popular JavaScript module bundler, building upon the solid foundation established by version 2.4.2. Both versions maintain identical core functionality, retaining the same dependencies crucial for transforming Node.js-style modules for use within web browsers. Developers relying on Browserify's core task of enabling require() statements in client-side code will find the fundamental behavior unchanged. The dependency tree remains consistent, ensuring that crucial packages like through, duplexer, inherits, optimist, JSONStream, module-deps, shell-quote, browser-pack, syntax-error, browser-resolve, and insert-module-globals continue to function as expected. Similarly, the development dependencies, including seq, tap, dnode, mkdirp, backbone, and coffee-script, used for testing and development workflows, are also held constant. The licensing remains under the MIT license, guaranteeing freedom in usage and modification. The key difference lies in the release date. Version 2.4.3 was released on March 6th, 2013, a day later than version 2.4.2, which was released on March 5th, 2013. This suggests that version 2.4.3 likely addresses minor bug fixes, performance tweaks, or very subtle improvements that didn't warrant a major or minor version increment. Therefore, developers currently using version 2.4.2 should consider upgrading to 2.4.3 to benefit from potential stability improvements or minor enhancements. However, the changes are not drastic, ensuring a smooth transition without requiring significant code modifications.
All the vulnerabilities related to the version 2.4.3 of the package
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.
Incorrect Handling of Non-Boolean Comparisons During Minification in uglify-js
Versions of uglify-js prior to 2.4.24 are affected by a vulnerability which may cause crafted JavaScript to have altered functionality after minification.
Upgrade UglifyJS to version >= 2.4.24.
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;");
