Debug version 2.3.0 introduces a subtle yet significant update to the popular debugging utility, primarily impacting its dependency on the ms package, which is bumped from version 0.7.1 to 0.7.2. While seemingly minor, this dependency update could include bug fixes, performance improvements, or security patches within the ms package, which developers indirectly benefit from. Developers relying on precise time conversions or human-readable time representations within their debugging workflows should particularly note this change, as it ensures they're leveraging the latest improvements in the ms time formatting library.
Beyond the dependency update, both versions maintain consistent functionality, offering a lightweight and versatile solution for adding debugging statements to Node.js and browser-based applications. The library allows developers to selectively enable or disable debug logs based on namespaces, providing granular control over debugging output. The core features remain the same: simple integration, namespace-based filtering, and browser/Node.js compatibility. Both versions are licensed under the MIT license, ensuring freedom and flexibility in its usage. The development dependencies, including mocha for testing and browserify for browser packaging, remained unchanged in this release. Therefore, the upgrade path from 2.2.0 to 2.3.0 should be relatively straightforward for most users, offering the advantages of the potentially improved ms dependency without significant code changes within the debug package itself.
All the vulnerabilities related to the version 2.3.0 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.
