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 βfreeβ, the issue can be potentially exploited only in a multi-threaded environment. In the worst case this may lead to code execution.
