Summary

stb security update

Details

Single-file public domain libraries for C/C++.

Security Fix(es):

stb_image is a single file MIT licensed library for processing images. It may look like stbi__load_gif_main doesn’t give guarantees about the content of output value *delays upon failure. Although it sets *delays to zero at the beginning, it doesn’t do it in case the image is not recognized as GIF and a call to stbi__load_gif_main_outofmem only frees possibly allocated memory in *delays without resetting it to zero. Thus it would be fair to say the caller of stbi__load_gif_main is responsible to free the allocated memory in *delays only if stbi__load_gif_main returns a non null value. However at the same time the function may return null value, but fail to free the memory in *delays if internally stbi__convert_format is called and fails. Thus the issue may lead to a memory leak if the caller chooses to free delays only when stbi__load_gif_main didn’t fail or to a double-free if the delays is always freed(CVE-2023-45666)

stb_image is a single file MIT licensed library for processing images.

If stbi__load_gif_main in stbi_load_gif_from_memory fails it returns a null pointer and may keep the z variable uninitialized. In case the caller also sets the flip vertically flag, it continues and calls stbi__vertical_flip_slices with the null pointer result value and the uninitialized z value. This may result in a program crash.(CVE-2023-45667)

Title

Possible double-free or memory leak in stbi__load_gif_main in stb_image

Summary

stb_image is a single file MIT licensed library for processing images. It may look like `stbi__load_gif_main` doesn’t give guarantees about the content of output value `*delays` upon failure. Although it sets `*delays` to zero at the beginning, it doesn’t do it in case the image is not recognized as GIF and a call to `stbi__load_gif_main_outofmem` only frees possibly allocated memory in `*delays` without resetting it to zero. Thus it would be fair to say the caller of `stbi__load_gif_main` is responsible to free the allocated memory in `*delays` only if `stbi__load_gif_main` returns a non null value. However at the same time the function may return null value, but fail to free the memory in `*delays` if internally `stbi__convert_format` is called and fails. Thus the issue may lead to a memory leak if the caller chooses to free `delays` only when `stbi__load_gif_main` didn’t fail or to a double-free if the `delays` is always freed

It may look like `stbi__load_gif_main` doesn\u2019t give guarantees about the content of output value `*delays` upon failure. Although it sets `*delays` to zero at the beginning, it doesn\u2019t do it in case the image is not recognized as GIF and a call to `stbi__load_gif_main_outofmem` only frees possibly allocated memory in `*delays` without resetting it to zero. Thus it would be fair to say the caller of `stbi__load_gif_main` is responsible to free the allocated memory in `*delays` only if `stbi__load_gif_main` returns a non null value. However at the same time the function may return null value, but fail to free the memory in `*delays` if internally `stbi__convert_format` is called and fails. Thus the issue may lead to a memory leak if the caller chooses to free `delays` only when `stbi__load_gif_main` didn\u2019t fail or to a double-free if the `delays` is always freed"

CVE-2023-45667 (GCVE-0-2023-45667)

Vulnerability from cvelistv5 – Published: 2023-10-20 23:26 – Updated: 2025-02-13 17:14

Title

Null pointer dereference because of an uninitialized variable in stb_image

Summary

stb_image is a single file MIT licensed library for processing images. If `stbi__load_gif_main` in `stbi_load_gif_from_memory` fails it returns a null pointer and may keep the `z` variable uninitialized. In case the caller also sets the flip vertically flag, it continues and calls `stbi__vertical_flip_slices` with the null pointer result value and the uninitialized `z` value. This may result in a program crash.

Severity

5.3 (Medium)
