CVE-2026-10194Network attack vector

Authenticated memory corruption via unbounded image indexing

Published May 31, 2026 · Updated May 31, 2026

Heap-based buffer overflow in OFFIS DCMTK 3.7.0 dcmqrscp allows remote authenticated users to corrupt process memory. During quota-driven deletion, deleteOldestImages appends matching index records to StudyArray while incrementing nbimages without enforcing MAX_NUMBER_OF_IMAGES. DICOM peer access and quota-triggered deletion are required; public sources confirm memory corruption but not code execution.
