CVE-2026-5437
HIGHOrthanc DICOM Server - Out-of-bounds Read in DicomStreamReader
Title source: llmDescription
An out-of-bounds read vulnerability exists in `DicomStreamReader` during DICOM meta-header parsing. When processing malformed metadata structures, the parser may read beyond the bounds of the allocated metadata buffer. Although this issue does not typically crash the server or expose data directly to the attacker, it reflects insufficient input validation in the parsing logic.
