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. A crafted image file may trigger out of bounds memcpy read in stbi__gif_load_next. This happens because two_back points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory allocation information.(CVE-2023-45661)

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.(CVE-2023-45664)

Severity

7.3 (High)

CVE-2023-45664 (GCVE-0-2023-45664)

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

Title

Double-free in stbi__load_gif_main_outofmem in stb_image

Summary

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.

Severity
