QUnitjs version 2.4.1 is a minor release following 2.4.0, presenting key updates for JavaScript unit testing. Both versions maintain the core promise of an easy-to-use framework, but several development dependency upgrades distinguish 2.4.1. Crucially, eslint-plugin-html jumps from 1.7.0 to 3.1.1, suggesting improvements in HTML linting rules - developers leveraging QUnit for testing web applications might benefit from more robust HTML validation during their testing workflows. Similarly, eslint-plugin-qunit moves from 2.3.0 to 3.2.0, signaling enhanced QUnit-specific linting, likely catching more potential issues in test code and promoting better testing practices. grunt-eslint also sees an upgrade from 19.0.0 to 20.0.0, providing a newer set of ESLint rules during the Grunt build process which can improve code quality by finding and automatically fixing problems. Code using QUnit will benefit from these changes. The author URL links to different file versions of contributors, suggesting minor changes to the contributor list. The core dependencies remain consistent, ensuring backward compatibility for users relying on existing functionalities. This update focuses on refined developer tooling with enhanced linting, aiming for a more streamlined and robust testing experience making it a worthwhile upgrade for developers keen on a clean and well-validated codebase by using the latest ESLint features.
All the vulnerabilities related to the version 2.4.1 of the package
Regular Expression Denial of Service (ReDoS) in micromatch
The NPM package micromatch prior to version 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in micromatch.braces() in index.js because the pattern .* will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persisted prior to https://github.com/micromatch/micromatch/pull/266. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.
Regular Expression Denial of Service (ReDoS) in braces
A vulnerability was found in Braces versions prior to 2.3.1. Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks.
Regular Expression Denial of Service in braces
Versions of braces prior to 2.3.1 are vulnerable to Regular Expression Denial of Service (ReDoS). Untrusted input may cause catastrophic backtracking while matching regular expressions. This can cause the application to be unresponsive leading to Denial of Service.
Upgrade to version 2.3.1 or higher.
Uncontrolled resource consumption in braces
The NPM package braces fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In lib/parse.js, if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.
