Browserify is a powerful tool for JavaScript developers, enabling the use of Node.js-style modules within browser environments. Comparing versions 3.29.1 and 3.29.0 reveals minimal difference. Both versions share the same core functionality of bundling JavaScript code and managing dependencies for client-side execution. They also share identical dependency trees, encompassing crucial packages like 'umd', 'url', 'resolve', 'through', 'module-deps', and numerous browser-specific shims for core Node.js modules. Both lists of devDependencies are also identical. This means that developers upgrading from 3.29.0 to 3.29.1 can expect nearly identical behavior and API interactions.
The primary distinction lies in their release dates. Version 3.29.1 was published on February 15, 2014, while 3.29.0 was released two days prior. Given the largely equivalent feature sets, this suggests that the update was potentially a patch addressing minor packaging or documentation issues rather than involving substantial code modifications.
For developers considering Browserify, these versions offer a solid foundation for building modular browser applications. Browserify handles the complexities of dependency resolution and module loading, creating a single bundle suitable for deployment. The included shims ensure compatibility with Node.js APIs, allowing developers to reuse existing server-side code or libraries in the browser thus improving code reuse and speeding up development. However, developers should investigate more recent versions of Browserify for security updates and bug fixes.
All the vulnerabilities related to the version 3.29.1 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
real 0m1.091s
user 0m1.047s
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.
