CVE-2023-47993Public exploitNetwork attack vector

Application crash via unchecked EXIF directory entry count

Published Jan 9, 2024 · Updated Jun 20, 2025

Out-of-bounds read in FreeImage 3.18.0 allows attackers to crash applications that process a crafted JPEG image. In jpeg_read_exif_dir, an EXIF directory-entry count controls pointer arithmetic for the next-IFD offset without a bounds check before ReadUint32 reads four bytes. Exploitation requires an application to process the crafted image; the supported consequence is an application crash.
