The debug package, a small yet effective debugging utility for Node.js and browsers, saw a minor version bump from 0.1.0 to 0.2.0. While the core functionality likely remained consistent, this release, dated January 22, 2012, comes approximately a month and a half after version 0.1.0 released on December 2, 2011. This suggests the changes between the versions may be limited to bug fixes, minor enhancements, or dependency updates although the provided metadata does not surface any of those differences.
Both versions share the same description and development dependency on Mocha, indicating a continued focus on testing. The author, TJ Holowaychuk, remains consistent across both versions. Developers considering using debug should note the relatively old release dates. Although the core concept of a simple debugging utility is timeless, later versions of the debug package have since been released and thus developers should explore them to take advantage of newer features, stability improvements, and security patches. Given the minimal information provided, selecting one version over the other is difficult, however, developers should download and inspect the tarball contents or explore more recent versions. Also, due to the age of the package, it is important to check for security concerns that may have affected these versions.
All the vulnerabilities related to the version 0.2.0 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.
