Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Pixmeo OsiriX MD is vulnerable to a use after free scenario, which could allow an attacker to upload a crafted DICOM file and cause memory corruption leading to a denial-of-service condition.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Pixmeo OsiriX MD contains a use-after-free vulnerability in its DICOM file parsing functionality. An attacker can trigger this vulnerability by uploading a specially crafted DICOM file, causing memory corruption that leads to denial of service.

MitigationImplement proper memory management in the DICOM parser, ensuring all allocated memory is freed before pointers are reused. Validate DICOM file structure before processing and consider deploying input validation and file type verification at upload points.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify OsiriX MD is installed
    Search for OsiriX MD application in the system: on macOS check /Applications folder or use 'find /Applications -name '*OsiriX*' -type d' command; on Windows check Program Files directories or use Get-ItemProperty registry key for installed software
    Affected if OsiriX MD software is present on the system
  2. Identify installed OsiriX MD version
    On macOS, right-click OsiriX MD.app > Get Info > Version, or run 'defaults read /Applications/OsiriX\ MD.app/Contents/Info CFBundleShortVersionString'; on Windows check file properties of the executable or examine version info in registry
    Affected if Installed version cannot be determined or falls within any vulnerable version range (compare against vendor release notes for CVE-2025-27578)
  3. Confirm DICOM file processing is accessible
    Check if DICOM import, upload, or parsing functionality is available: look for DICOM listener services, web upload interfaces, or local file import features in the application
    Affected if DICOM file parsing functionality is enabled and accessible to users or external systems
  4. Review access to DICOM file upload points
    Examine network-exposed interfaces where DICOM files can be uploaded: web portals, DICOM C-STORE SCP services, API endpoints accepting DICOM uploads, or shared network folders processed by OsiriX MD
    Affected if Untrusted DICOM files can be uploaded or received by the OsiriX MD system without prior sanitization
  5. Check for crash logs or memory corruption indicators
    Review system logs, application crash reports, and security logs for evidence of unexpected crashes related to DICOM file processing: on macOS check ~/Library/Logs and Console.app; on Windows check Event Viewer Application logs
    Affected if Unexpected crashes or memory corruption events occur when processing DICOM files

The environment is affected if OsiriX MD is installed with DICOM parsing enabled and external users or systems can supply DICOM files to the system, particularly through upload interfaces.
