CVE-2025-53618
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 · uneditedAn 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 confidenceAn 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Grassroots DICOM versionRun 'gdcmdump --version' or check the application's version information via package manager, binary metadata, or library version fileAffected if The installed version is exactly 3.0.24 (the only affected version listed)
-
Locate the JPEGBITSCodec library componentSearch for files containing 'JPEGBITSCodec' or 'jpegbits' in the installation directory, typically under lib/ or bin/ folders of the Grassroots DICOM packageAffected if The JPEGBITSCodec library (jpegbitscodec.dll, libjpegbitscodec.so, or similar) is present and loadable
-
Verify DICOM file processing capability is enabledCheck if the application has modules or plugins enabled for DICOM image decoding - look for configuration files or runtime module listings that show codec availabilityAffected if DICOM codec modules including JPEG processing are enabled or auto-loaded
-
Identify if application processes external DICOM filesReview application logs, configurations, or user-accessible import features that accept DICOM files as inputAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement 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.
