CVE-2026-5185 Details
Description
A security flaw has been discovered in Nothings stb_image up to 2.30. This affects the function stbi__gif_load_next of the file stb_image.h of the component Multi-frame GIF File Handler. The manipulation results in heap-based buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A heap-based buffer overflow vulnerability has been identified in Nothings stb_image versions through 2.30. The issue arises in the function 'stbi__gif_load_next' within 'stb_image.h', specifically in the Multi-frame GIF File Handler component. The vulnerability is triggered by a crafted multi-frame GIF file, which exploits an incorrectly calculated pointer, leading to an out-of-bounds memory read. This manipulation causes a heap-buffer-overflow condition, with potential impacts including information disclosure through a heap memory leak and a denial-of-service by causing a crash.
