Debug version 2.4.2 introduces several notable changes compared to its predecessor, 2.4.1, primarily focused on enhancing the development workflow and code quality. While both versions maintain the core functionality of a small debugging utility and share the same dependency on ms (version 0.7.2), the newer release incorporates a suite of updated development dependencies.
Specifically, version 2.4.2 adds a comprehensive toolchain for modern JavaScript development. This includes Babel for transpiling ES2015+ code, Chai and Sinon for robust testing with assertions and mocking, and ESLint for enforcing code style and preventing errors. The inclusion of babel-eslint and eslint-plugin-babel ensures seamless integration of ESLint with Babel's transpiled code. Furthermore, babel-runtime, babel-polyfill, and babel-register provide the necessary runtime environment and helpers for modern JavaScript features, ensuring compatibility across different environments, and babel-preset-es2015 dictates which versions of the ecmascript specifications are taken into account when transpiling the code.
Version 2.4.2 notably adds a more robust and standardized development environment. Developers upgrading from 2.4.1 will benefit from improved code maintainability, more comprehensive testing capabilities, and a more streamlined workflow for developing with modern JavaScript syntax. These additions reflect a commitment to code quality and a better developer experience. While end-users of the debug library might not notice a direct change in runtime behavior, the improved development process ultimately contributes to a more stable and reliable debugging tool.
All the vulnerabilities related to the version 2.4.2 of the package
debug Inefficient Regular Expression Complexity vulnerability
A vulnerability classified as problematic has been found in debug-js debug up to 3.0.x. This affects the function useColors of the file src/node.js. The manipulation of the argument str leads to inefficient regular expression complexity. Upgrading to version 3.1.0 is able to address this issue. The name of the patch is c38a0166c266a679c8de012d4eaccec3f944e685. It is recommended to upgrade the affected component. The identifier VDB-217665 was assigned to this vulnerability. The patch has been backported to the 2.6.x branch in version 2.6.9.
Regular Expression Denial of Service in debug
Affected versions of debug are vulnerable to regular expression denial of service when untrusted user input is passed into the o formatter.
As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.
This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1.
Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
Vercel ms Inefficient Regular Expression Complexity vulnerability
A vulnerability, which was classified as problematic, has been found in vercel ms up to 1.x. This issue affects the function parse of the file index.js. The manipulation of the argument str leads to inefficient regular expression complexity. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.0.0 is able to address this issue. The name of the patch is caae2988ba2a37765d055c4eee63d383320ee662. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-217451.
