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
An out-of-bounds read vulnerability exists in the JPEGBITSCodec::InternalCode functionality of Grassroot DICOM 3.024. A specially crafted DICOM file can lead to an information leak. An attacker can provide a malicious file to trigger this vulnerability.The function `grayscale_convert` is called based of the value of the malicious DICOM file specifying the intended interpretation of the image pixel data

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 · high confidence

An out-of-bounds read vulnerability exists in the JPEGBITSCodec::InternalCode functionality of Grassroot DICOM 3.024. A specially crafted DICOM file with a malicious pixel data interpretation value triggers the grayscale_convert function to read beyond allocated memory boundaries, leading to information disclosure.

MitigationImplement strict bounds validation on pixel data interpretation values from DICOM files before calling grayscale_convert; validate all array indices and buffer sizes in the JPEG codec path.

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. Identify installed Grassroots DICOM version
    Run 'gdcmdump --version' or check the application's version information via package manager, binary metadata, or library version file
    Affected if The installed version is exactly 3.0.24 (the only affected version listed)
  2. Locate the JPEGBITSCodec library component
    Search for files containing 'JPEGBITSCodec' or 'jpegbits' in the installation directory, typically under lib/ or bin/ folders of the Grassroots DICOM package
    Affected if The JPEGBITSCodec library (jpegbitscodec.dll, libjpegbitscodec.so, or similar) is present and loadable
  3. Verify DICOM file processing capability is enabled
    Check if the application has modules or plugins enabled for DICOM image decoding - look for configuration files or runtime module listings that show codec availability
    Affected if DICOM codec modules including JPEG processing are enabled or auto-loaded
  4. Identify if application processes external DICOM files
    Review application logs, configurations, or user-accessible import features that accept DICOM files as input
    Affected if The application accepts DICOM files from users or external sources without prior validation

A user is affected if they are running version 3.0.24 of Malaterre Grassroots DICOM with the JPEGBITSCodec enabled and the ability to process external DICOM files.
