CVE-2026-10194: OFFIS DCMTK dcmqrscp dcmqrdbi.cc deleteOldestImages heap-based overflow

A weakness has been identified in OFFIS DCMTK 3.7.0. This affects the function DcmQueryRetrieveIndexDatabaseHandle::deleteOldestImages of the file dcmqrdb/libsrc/dcmqrdbi.cc of the component dcmqrscp. Executing a manipulation can lead to heap-based buffer overflow. The attack may be launched remotely. This patch is called 0f78a4ef6f645ea5530166e445e5436a5de58e75. A patch should be applied to remediate this issue.

Security readout for executives and security teams

Plain-English summary

CVE-2026-10194 affects OFFIS DCMTK 3.7.0, specifically the dcmqrscp DICOM query/retrieve service. A remote authenticated user may trigger a heap-based buffer overflow, potentially affecting confidentiality, integrity, and availability. It is not listed as KEV, and the provided sources do not show active exploitation.

Executive priority

Treat as a moderate-priority healthcare imaging infrastructure issue. Prioritize internet- or partner-exposed dcmqrscp services, then internal deployments. The main concern is service disruption or compromise by an authenticated remote user, not confirmed mass exploitation.

Technical view

The issue is in DcmQueryRetrieveIndexDatabaseHandle::deleteOldestImages in dcmqrdb/libsrc/dcmqrdbi.cc within dcmqrscp. The reported weakness is CWE-119/CWE-122 heap-based buffer overflow. VulDB assigns CVSS v2 6.5 with network access, low complexity, and single authentication required. Patch commit 0f78a4ef6f645ea5530166e445e5436a5de58e75 is cited.

Likely exposure

Exposure is most likely where DCMTK 3.7.0 runs dcmqrscp as a DICOM query/retrieve SCP reachable by authenticated remote users. The bundle does not identify other affected versions or products.

Exploitation context

The sources state remote attack is possible and authentication is required. There is no KEV listing in the bundle and no cited evidence of active exploitation. The referenced patch URL is marked broken-link in the bundle, so patch verification may require vendor confirmation.

Researcher notes

Evidence is limited to the CVE/VulDB bundle. Confirm affected code paths against local DCMTK 3.7.0 builds and validate whether the cited patch is incorporated. Avoid assuming exploitability beyond the stated remote authenticated heap overflow.

Mitigation direction

  • Identify systems running OFFIS DCMTK 3.7.0 with dcmqrscp enabled.
  • Apply the cited patch or vendor-confirmed fixed DCMTK release.
  • Restrict dcmqrscp access to trusted DICOM clients where possible.
  • Review vendor guidance if patch retrieval or version coverage is unclear.
  • Monitor affected services for crashes or abnormal memory-related failures.

Validation and detection

  • Inventory DCMTK package versions and dcmqrscp deployments.
  • Confirm whether commit 0f78a4ef6f645ea5530166e445e5436a5de58e75 is present.
  • Check whether dcmqrscp is reachable from untrusted networks.
  • Verify authentication is required for exposed DICOM query/retrieve workflows.
  • Review VulDB CTI references for any published indicators.
