Grassroots Dicom Gdcm
Monthly
Malformed DICOM files with non-standard VR types trigger uncontrolled memory allocation in Grassroots DICOM (GDCM) library, enabling remote denial-of-service attacks without authentication. CISA ICS-CERT issued an ICSMA advisory (26-083-01) highlighting impacts to medical imaging systems that rely on GDCM for DICOM parsing. The vulnerability allows heap exhaustion from a single malicious file read operation, with CVSS 7.5 (High severity, network-accessible, no privileges required). No public exploit identified at time of analysis.
