Debug versions 2.6.5 and 2.6.4 are minimal updates to this widely used small debugging utility for Node.js and browsers. Both versions, licensed under MIT, share the same core functionality for selectively enabling and disabling debugging output, making it incredibly useful for developers tracing code execution and pinpointing issues. They depend only on "ms" version 0.7.3, a tiny library for converting various time formats to milliseconds, showcasing the efficiency of the debug package itself. The developer dependencies, identical in both versions, highlight the robust testing and linting environment: Chai, Mocha, and Sinon enable comprehensive unit testing with assertions, mocking, and spying, while ESLint ensures code quality and consistency. Tools like Istanbul and Coveralls indicate a commitment to code coverage analysis. Browserify enables bundling for browser usage, and Karma facilitates cross-browser testing.
The key difference lies in the release date; version 2.6.5 was published on April 27, 2017, a week after version 2.6.4 released on April 20, 2017. Considering the small change in version numbers, it likely contains very minor bug fixes or internal improvements that didn’t warrant a major or minor version bump. For developers, this means upgrading from 2.6.4 to 2.6.5 should be a safe and straightforward process, as the API remains consistent. Developers can continue using debug with confidence, enabling targeted logging through environment variables, leveraging its simple yet powerful approach to debugging their applications across different environments.
All the vulnerabilities related to the version 2.6.5 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.
