CVE-2025-25472

Denial of service via out-of-range background fill

Published Feb 18, 2025 · Updated Nov 3, 2025

Buffer overflow in DCMTK 3.6.9+ DEV allows attackers to cause a denial of service via a crafted monochrome DCM file. When an invalid image supplies fewer stored pixels than its declared matrix, DiMonoInputPixelTemplate fills the remainder using an out-of-range modality minimum. A DCMTK-based application must process the file; public records do not identify the exact failure mode or report code execution.
