Browserify, a widely-used npm package offering browser-side require() functionality mirroring Node.js's module system, saw a minor version update from 2.34.2 to 2.34.3 on October 17, 2013. Both versions share the same core description and maintainer, James Halliday, indicating a consistent project vision. The crucial dependencies, those packages Browserify relies on to function, remain identical between the two versions, encompassing utilities like umd, through, duplexer, and essential modules for dependency management (module-deps, deps-sort) and browser compatibility (browser-resolve, browser-builtins). This signifies stability in Browserify's core architecture. Similarly, development dependencies used for testing and building, such as tap, dnode, and coffee-script, are also unchanged, suggesting no major shifts in the development workflow.
The primary difference lies in the release date, with version 2.34.3 appearing shortly after 2.34.2. While no dependency changes are apparent in the metadata, this minor version bump likely addresses bug fixes, performance improvements, or superficial updates. Developers already using Browserify 2.34.2 should consider upgrading to 2.34.3 for potentially enhanced stability and minor refinements. Users not yet utilizing Browserify can confidently adopt either version; however, opting for the slightly newer 2.34.3 is generally recommended to benefit from any potential incremental improvements. Keep in mind this package is quite old so before adopting it look at more modern alternatives if possible.
All the vulnerabilities related to the version 2.34.3 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;");

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.
