CVE-2022-43272Public exploitNetwork attack vector

Service interruption via unreleased DICOM associations

Published Dec 2, 2022 · Updated Nov 3, 2025

Memory leak in dcmqrscp single-process mode in OFFIS DCMTK 3.6.7 allows remote attackers to exhaust memory via DICOM associations. DcmQueryRetrieveSCP::waitForAssociation conditionally skipped ASC_dropAssociation and ASC_destroyAssociation in single-process mode, leaving each T_ASC_Association allocated. An unauthenticated peer able to open repeated DICOM associations can consume server memory and interrupt the service.
