CVE-2023-32284Public exploitNetwork attack vector

Memory corruption via unchecked planar TIFF write

Published Sep 25, 2023 · Updated Nov 4, 2025

An out-of-bounds write in Accusoft ImageGear 20.1 allows remote attackers to corrupt memory by supplying a malformed TIFF file. The tiff_planar_adobe routine derives a raster-buffer size from TIFF ImageWidth, then an attacker-controlled loop writes past that buffer without a bounds check. The host application must pass the crafted file to the TIFF decoder; the documented consequence is memory corruption and an application crash.
