Technical details
A memory leak vulnerability (CWE-401) exists in the OFFIS DCMTK Toolkit, specifically affecting the 'storescp' component. An unauthenticated remote attacker can exploit this by sending a series of crafted connection requests over the network. In the default single-process mode, these requests cause rapid memory consumption until the process is terminated by the operating system. Once the service is killed, it stops accepting new DICOM connections until manually restarted. The maintainer has released a fix available in the latest GitHub repository snapshots.
