CVE-2026-102805: stb image integer overflow in PNG/JPEG/TGA encoding

CVE-2026-102805 · Severity: medium · CVSS 6.5 · Published 2026-09-30

A flaw in the stb image encoding library allows attackers to trigger an integer overflow when encoding PNG, JPEG, or TGA images. This can lead to heap buffer overflow or out-of-bounds memory reads. An attacker can exploit this remotely by providing a specially crafted image, potentially causing application crashes, information disclosure, or code execution.

Technical details

An integer overflow vulnerability exists in stb_image_write.h functions stbi_write_png_to_mem, stbi_write_jpg_core, and stbi_write_tga_core, triggered during image dimension calculations. The vulnerability is remotely exploitable through the manipulation of image encoding operations and can result in heap buffer overflow (PNG) or out-of-bounds reads (JPEG/TGA). A fix is available through library updates.
