CVE-2019-1010228: OFFIS.de DCMTK 3.6.3 and below is affected by: Buffer Overflow.

OFFIS.de DCMTK 3.6.3 and below is affected by: Buffer Overflow. The impact is: Possible code execution and confirmed Denial of Service. The component is: DcmRLEDecoder::decompress() (file dcrledec.h, line 122). The attack vector is: Many scenarios of DICOM file processing (e.g. DICOM to image conversion). The fixed version is: 3.6.4, after commit 40917614e.

Security readout for executives and security teams

Plain-English summary

DCMTK versions 3.6.3 and earlier can overflow memory while processing certain DICOM data. The reported impact includes confirmed denial of service and possible code execution. Organizations that convert, import, or otherwise process DICOM files with DCMTK should treat this as a serious file-processing risk.

Executive priority

Prioritize remediation where DCMTK processes DICOM files from outside trusted clinical or operational boundaries. The main business risk is service disruption, with possible code execution reported but not fully scored in the provided sources.

Technical view

The reported vulnerable component is DcmRLEDecoder::decompress() in dcrledec.h. The attack vector is DICOM file processing, including DICOM-to-image conversion. The source bundle states the fix is DCMTK 3.6.4 after commit 40917614e, but provides no CVSS score or CWE mapping.

Likely exposure

Exposure is most likely in applications, services, or imaging workflows that use DCMTK 3.6.3 or earlier to parse, decode, convert, or ingest DICOM files, especially files from external or semi-trusted sources.

Exploitation context

The bundle does not cite active exploitation, and KEV status is false. Exploitation would require a crafted DICOM processing path reaching the vulnerable RLE decompression code. Public evidence in the bundle supports denial of service and possible code execution, but not weaponization status.

Researcher notes

Key unknowns remain: no CVSS vector, no CWE assignment, and no cited active exploitation. Focus validation on version identification, bundled dependencies, and DICOM processing paths that can reach DcmRLEDecoder::decompress().

Mitigation direction

  • Upgrade DCMTK to version 3.6.4 or later where feasible.
  • Confirm downstream products are not bundling DCMTK 3.6.3 or earlier.
  • Restrict DICOM ingestion to trusted sources until vendor fixes are confirmed.
  • Check vendor guidance for product-specific patches or compensating controls.

Validation and detection

  • Inventory applications and packages that include or link against DCMTK.
  • Verify the deployed DCMTK version is 3.6.4 or later.
  • Review DICOM conversion and ingestion services for external file exposure.
  • Confirm Fedora or vendor advisory updates are applied where relevant.
