Debug version 2.6.2 is a minor update to the popular small debugging utility for Node.js and browsers, following version 2.6.1. Both versions, authored by TJ Holowaychuk, share identical core functionality, providing a simple yet powerful mechanism for enabling and disabling debug messages within your application. They both rely on the "ms" package version 0.7.2 as a dependency for human-readable time differences. Their development dependencies, used for testing and building the packages, are exactly the same. These include testing frameworks like Chai, Mocha, and Sinon, along with tools for linting (ESLint), code coverage (Istanbul and Coveralls), and browser bundling (Browserify). Karma is employed as the test runner, supported by various plugins for seamless integration with the testing frameworks. Concurrent execution during development is facilitated by the "concurrently" package.
The primary distinction lies in the release date and the tarball URL. Version 2.6.2 was released on March 10, 2017, while version 2.6.1 was released on February 10, 2017. Therefore, developers should consider upgrading to 2.6.2 since it represents the latest stable version which eventually includes bug fixes and incremental improvements, even if not explicitly documented. Both versions are distributed under the MIT license, granting users broad permissions to use, modify, and distribute the software. The consistent development dependencies and licensing across both versions indicate that the core development workflow and usability remain unchanged. Developers using debug can expect a seamless transition when upgrading to the latest version.
All the vulnerabilities related to the version 2.6.2 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.
