Debug version 4.1.1 is a minor patch release following 4.1.0 of this widely used, small debugging utility for Node.js and browsers. Both versions share the same core functionality, providing a simple yet powerful mechanism to selectively enable and disable debugging output within applications. The debug package allows developers to instrument their code with informative messages that can be activated or suppressed based on environment variables or configuration settings. Key features include namespace support for categorizing debug messages and flexible output formatting.
Examining the metadata, the core dependencies remain consistent between versions 4.1.0 and 4.1.1 which is ms. The mspackage is responsible for parsing and formatting time durations and is fundamental to how debug displays timing information alongside debug messages. Similarly, the development dependencies like testing frameworks (Mocha, Chai, Karma), linting tools (XO), and build tools (Browserify, Babel) are identical, suggesting no significant changes in the development pipeline or testing strategy between these releases.
The notable distinction lies in the dist metadata. Version 4.1.1 has a slightly larger unpacked size (81476 bytes) compared to 4.1.0 (80172 bytes), likely indicating minor code fixes or small adjustments to included assets. Additionally, the releaseDate reveals that version 4.1.1 was published later, on December 22, 2018, compared to version 4.1.0 on October 8, 2018. Users should upgrade to version 4.1.1 to benefit from possible small bug fixes.
All the vulnerabilities related to the version 4.1.1 of the package
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.
