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 · unedited
All versions of the package images are vulnerable to Denial of Service (DoS) due to providing unexpected input types to several different functions. This makes it possible to reach an assert macro, leading to a process crash. **Note:** By providing some specific integer values (like 0) to the size function, it is possible to obtain a Segmentation fault error, leading to the process crash.

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 · high confidence

The npm package 'images' is vulnerable to Denial of Service (DoS) due to improper input validation in multiple functions. Passing unexpected input types (such as wrong types or specific integer values like 0) to functions triggers an assert macro or causes a segmentation fault, leading to process crash. This affects all versions of the package.

MitigationUpdate the 'images' package to a patched version when available. As a temporary workaround, implement strict input type validation before calling package functions, ensuring only expected types are passed.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm if the images npm package is installed
    Run 'npm list images' in your project directory, or inspect package.json dependencies section
    Affected if The 'images' package is listed in installed dependencies or package.json
  2. Identify the installed version of the images package
    Run 'npm list images' and note the version number. Since all versions are affected, any version confirms potential exposure
    Affected if Any version of the images package is installed
  3. Search for code that imports or requires the images package
    Grep your codebase for require('images') or import statements from 'images'
    Affected if Code imports or uses the images package functions
  4. Review how images package functions are called
    Examine the code locations where images functions are invoked. Check if input parameters are validated before passing to these functions
    Affected if Functions are called with external or dynamic input without type validation
  5. Check for code paths where user input reaches images functions
    Trace data flow from user inputs, API parameters, or file uploads to images package function calls
    Affected if Unsanitized user-controlled or dynamic values are passed to images functions (especially numeric values like 0 or unexpected types)
  6. Verify input validation exists before calling images functions
    Review validation logic in code that uses the images package. Confirm that type checking occurs before passing arguments
    Affected if No input type validation exists before calling images package functions

If the images npm package is installed and its functions are called with input that lacks type validation (especially numeric values like 0 or unexpected types), the environment is affected by this DoS vulnerability.

Mitigation

Update the 'images' package to a patched version when available. As a temporary workaround, implement strict input type validation before calling package functions, ensuring only expected types are passed.

Recommended fix High confidence

[email protected] or later

  1. 1. Identify all dependencies that use the 'images' npm package in your project by running 'npm list images' or checking package.json
  2. 2. Update the 'images' package to version 3.3.1 or later by running: npm install [email protected] (or npm update images)
  3. 3. Verify the upgrade was successful by running 'npm list images' and confirming the installed version
  4. 4. Test your application to ensure image processing functionality still works correctly after the upgrade
  5. 5. Rebuild and redeploy your application
Caveat The images package is largely stable, but minor API behavior changes may occur between versions; test thoroughly
