        Path traversal issues were found, allowing an attacker
        to write DICOM files into arbitrary directories under
        controlled names. This could allow remote code execution.

    CVE-2024-47796

        An improper array index validation vulnerability exists
        in the nowindow functionality.
        A specially crafted DICOM file can lead to an out-of-bounds write.

    CVE-2025-2357

        An issue was found in the dcmjpls JPEG-LS Decoder.
        The manipulation leads to memory corruption.

    CVE-2025-25472
