Debug is a lightweight yet powerful debugging utility for Node.js and browsers, designed to selectively enable debugging statements based on namespaces. The 2.6.4 release, published on April 20, 2017, builds upon the stable 2.6.3 version released a month earlier. While both versions share the same core functionality, author, license (MIT), and development dependencies for testing and linting, the key difference lies in their dependency on the ms package. Version 2.6.4 updates this dependency to ms@0.7.3 from ms@0.7.2 in the prior version. The ms package is used by debug to convert time strings (such as '2d' or '1h') to milliseconds. This seemingly minor update in ms is the primary change between the two debug releases and might contain bug fixes, performance improvements, or new features within the ms package itself related to time conversions. Developers using debug should note this dependency update, as such updates might influence the precise timing or behavior of debugging output if they rely heavily on time-related features within the debug library. The package continues to be hosted on GitHub, and installable through npm or yarn.
All the vulnerabilities related to the version 2.6.4 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.
