Mocha version 2.5.3 represents a minor update to the popular JavaScript test framework, building upon the foundation laid by version 2.5.2. Both versions share the same core dependencies, including packages for diffing, globbing, templating with Jade, debugging, system notifications, directory creation, command-line argument parsing, ISO string conversion, color support, and regular expression escaping. The development dependencies also remain consistent, featuring tools for Karma test running, ESLint code linting, Should.js assertion library, streaming data transformation with Through2, Watchify for browserify bundling, Expect.js assertion, PhantomJS headless browser, Browserify module bundler, Karma Expect integration, CoffeeScript support, browser standard output capturing, Karma No Mocha integration, Karma Browserify integration, Karma Spec Reporter, Karma Sauce Launcher, and Karma PhantomJS Launcher.
The primary difference lies in the release date. Version 2.5.3 was published on May 25, 2016, just a day after version 2.5.2, which was released on May 24, 2016. This suggests that version 2.5.3 likely contains bug fixes or minor improvements addressing issues identified in the immediately preceding version. For developers using Mocha, upgrading from 2.5.2 to 2.5.3 is advisable to benefit from these potential fixes and ensure a smoother testing experience. Given the identical dependency declarations, compatibility should not be a concern for those already using 2.5.2. The updated version continues to provide a flexible and enjoyable testing environment for JavaScript applications, backed by a comprehensive suite of developer tools for quality assurance.
All the vulnerabilities related to the version 2.5.3 of the package
Regular Expression Denial of Service (ReDoS)
A vulnerability was found in diff before v3.5.0, the affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks.
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.
debug Inefficient Regular Expression Complexity vulnerability
A vulnerability classified as problematic has been found in debug-js debug up to 3.0.x. This affects the function useColors of the file src/node.js. The manipulation of the argument str leads to inefficient regular expression complexity. Upgrading to version 3.1.0 is able to address this issue. The name of the patch is c38a0166c266a679c8de012d4eaccec3f944e685. It is recommended to upgrade the affected component. The identifier VDB-217665 was assigned to this vulnerability. The patch has been backported to the 2.6.x branch in version 2.6.9.
Regular Expression Denial of Service in debug
Affected versions of debug
are vulnerable to regular expression denial of service when untrusted user input is passed into the o
formatter.
As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.
This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1.
Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
Vercel ms Inefficient Regular Expression Complexity vulnerability
A vulnerability, which was classified as problematic, has been found in vercel ms up to 1.x. This issue affects the function parse of the file index.js. The manipulation of the argument str leads to inefficient regular expression complexity. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.0.0 is able to address this issue. The name of the patch is caae2988ba2a37765d055c4eee63d383320ee662. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-217451.
Growl before 1.10.0 vulnerable to Command Injection
Affected versions of growl
do not properly sanitize input prior to passing it into a shell command, allowing for arbitrary command execution.
Update to version 1.10.0 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).
