Browserify, a cornerstone tool for bringing Node.js-style modules to the browser, saw a minor version bump from 3.24.8 to 3.24.9, offering subtle but noteworthy changes for developers. Both versions maintain the core functionality of enabling require() in browser environments, packaging dependencies for efficient client-side execution. The primary function remains consistent: allowing developers to write modular JavaScript code, leveraging the vast npm ecosystem, and deploying it seamlessly to web browsers.
The key difference lies in the dependency updates. Version 3.24.9 incorporates an updated module-deps dependency, moving from version 1.3.1 to ~1.4.0. This likely includes bug fixes, performance improvements, and potentially enhanced module resolution capabilities within the dependency graph. Also insert-module-globals was updated from ~3.0.0 to ~3.1.2 and syntax-error from ~0.0.0 to ~0.1.0. While seemingly minor, such updates are crucial for maintaining compatibility, stability, and security within the Browserify pipeline. Changes in insert-module-globals might have implications on how global variables are handled, potentially affecting browser compatibility or code execution. A syntax-error update suggests an improved error handling experience, thus making developer's debugging process easier.
Developers considering an upgrade should evaluate if their project is affected by the dependency upgrades, especially concerning any breaking changes that the dependencies could introduce. Overall, the update appears to be a refinement focusing on improved stability and updated module handling.
All the vulnerabilities related to the version 3.24.9 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 10000

sys 0m0.039s
$ time node test.js 80000
real 0m6.486s
user 0m6.229s
sys 0m0.094s
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.
