CVE-2026-5437
Orthanc DICOM Server
Out-of-Bounds Read in DicomStreamReader
CVSS 3.1
7.5High
Official description
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.
