CVE-2021-27585
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 · uneditedWhen a user opens manipulated Computer Graphics Metafile (.CGM) format files received from untrusted sources in SAP 3D Visual Enterprise Viewer version 9, the application crashes and becomes temporarily unavailable to the user until restart of the application.
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 confidenceA denial of service vulnerability exists in SAP 3D Visual Enterprise Viewer version 9 when parsing malformed Computer Graphics Metafile (.CGM) files. Opening a specially crafted CGM file from an untrusted source triggers a crash that renders the application unavailable until restart. The vulnerability stems from insufficient input validation or improper bounds checking in the CGM file parser.

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.
-
Confirm SAP 3D Visual Enterprise Viewer is installedLocate the application in the system Program Files directory, or check the installed programs list via Control Panel or system management toolsAffected if The application is present on the system
-
Identify the installed versionRight-click the executable (typically named 'SAP 3D Visual Enterprise Viewer.exe'), select Properties, and check the File Version field under the Details tab. Alternatively, run the application and look for the version number in the Help or About menuAffected if The version number is exactly 9.0 (or shows as version 9)
-
Determine if CGM file handling is availableCheck if the application can open or import .cgm file extensions by looking at supported file types in the application's Open dialog filter, or check file associations for .cgm files on the systemAffected if CGM files are listed as a supported format and can be opened by the viewer
-
Assess exposure to untrusted CGM filesReview whether the application is used to open CGM files from external or untrusted sources, or check recent file access logs for .cgm file openingsAffected if The application has been used to open CGM files from untrusted or unknown sources
A system is affected if SAP 3D Visual Enterprise Viewer version 9 is installed and can be used to open CGM files, since parsing a specially crafted CGM file from an untrusted source will trigger the denial of service.

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 dataUsers should avoid opening CGM files from untrusted or unknown sources. Organizations should deploy security updates from SAP when available and consider implementing network-based controls to block CGM file attachments from external sources.
