How to Fix GHSA-ppjr-267j-5p9x

To remediate this vulnerability, upgrade all affected Stb image dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

stb_image fixed: 0.2.5 
Upgrade stb_image to 0.2.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for stb_image

How to Check if You Are Affected

To determine whether your application is affected by GHSA-ppjr-267j-5p9x, inspect your project dependencies for Stb image:

inspect dependencies for stb_image

Analyze the terminal output to locate any version of Stb image in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-476: NULL Pointer Dereference, where the product dereferences a pointer that it expects to be valid but is null. In Stb image, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A bug in error handling in the `stb_image` C library could cause a NULL pointer dereference when attempting to load an invalid or unsupported image file. This is fixed in version 0.2.5 and later of the `stb_image` Rust crate, by patching the C code to correctly handle NULL pointers.
