An exploitable heap out of bounds write vulnerability exists in the UI tag parsing functionality of the DICOM image format of LEADTOOLS 20.0.2019.3.15. A specially crafted DICOM image can cause an offset beyond the bounds of a heap allocation to be written, potentially resulting in code execution. An attacker can specially craft a DICOM image to trigger this vulnerability.
