There is no fixed version for Debian:12 libstb.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libstb package and not the libstb package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
stb_image is a single file MIT licensed library for processing images. A crafted image file can trigger stbi__load_gif_main_outofmem attempt to double-free the out variable. This happens in stbi__load_gif_main because when the layers * stride value is zero the behavior is implementation defined, but common that realloc frees the old memory and returns null pointer. Since it attempts to double-free the memory a few lines below the first “free”, the issue can be potentially exploited only in a multi-threaded environment. In the worst case this may lead to code execution.
