Comment 2 Ben Beasley 2023-10-26 10:48:04 UTC 
This CVE appears to duplicate GHSL-2023-150/CVE-2023-45666 (bug 2246112) and GHSL-2023-148/CVE-2023-45664 (bug 2246106).
Comment 3 Ben Beasley 2023-10-26 10:53:25 UTC 
Additionally, the description as a remote denial of service is misleading: stb_image is a library that contains no network code of its own; a remote denial of service is possible when a specific application uses it to read untrusted images obtained via a network, but not, for example, if a game uses it to load its own “trusted” assets.
