CVE-2023-3576Public exploit

Local tiffcrop crash via unreleased input buffer

Published Oct 4, 2023 · Updated Jun 23, 2026

Memory leak in tiffcrop on Red Hat Enterprise Linux 8 and 9 allows local users to crash the utility with a crafted TIFF file. The loadImage function allocates an input buffer through limitMalloc, and a failure path leaves that allocation unreleased after processing malformed image data. Processing the crafted file is required; the reported consequence is memory exhaustion that crashes tiffcrop, with no confidentiality or integrity impact.
