CVE-2013-2024
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4.9.0.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOS command injection vulnerability in the 'qs' (quick sort) procedure from the 'utils' module in the Chicken Scheme interpreter/compiler. The vulnerability allows execution of arbitrary operating system commands through unsanitized input passed to the qs procedure, affecting versions prior to 4.9.0.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Chicken Scheme versionRun 'csi -version' or 'chicken -version' from the command line to display the interpreter/compiler versionAffected if The version displayed is 4.8.2 or earlier, or any version prior to 4.9.0
-
Confirm the utils module is in useSearch project source files for '(import utils)' or '(use utils)' statements, or for calls to the qs procedure such as '(qs ...)'Affected if Code imports or uses the utils module and calls the qs procedure
-
Inspect data flow into qs procedureReview all code paths that invoke qs and trace whether external input (command-line arguments, files, network data, environment variables) reaches this procedure unsanitizedAffected if Untrusted or user-controlled data is passed directly as arguments to the qs procedure without validation
-
Verify Debian package version if applicableOn Debian systems, run 'dpkg -l | grep chicken' or 'apt-cache policy chicken' to list installed Chicken package versionsAffected if The installed Debian chicken package version corresponds to a version of Chicken Scheme 4.8.2 or earlier
A user is affected if they run Chicken Scheme version 4.8.2 or earlier and their code passes untrusted input to the qs procedure from the utils module.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Chicken version 4.9.0 or later. If immediate patching is not possible, audit all code paths that invoke the qs procedure from utils and ensure no untrusted input reaches this function.
