CVE-2021-44422
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 Improper Input Validation Vulnerability exists when reading a BMP file using Open Design Alliance Drawings SDK before 2022.12. Crafted data in a BMP file can trigger a write operation past the end of an allocated buffer, or lead to a heap-based buffer overflow. An attacker can leverage this vulnerability to execute code in the context of the current process.
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 confidenceOpen Design Alliance Drawings SDK before version 2022.12 contains an improper input validation vulnerability when parsing BMP files. Crafted BMP data can trigger writes past the end of allocated buffers, resulting in heap-based buffer overflows. An attacker can exploit this to execute arbitrary code in the context of the current process.

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 Drawings SDK installationLocate the Open Design Alliance Drawings SDK installation directory and check the SDK version file or DLL properties. Common locations include program files or application-dependent directories. The version is typically displayed in the SDK binary or a versioninfo resource.Affected if The installed version is earlier than 2022.12
-
Verify BMP file parsing capabilityDetermine if BMP file parsing is enabled in your application configuration or if the SDK is configured to accept BMP input files. Check application settings, file type associations, or import/convert function parameters.Affected if BMP parsing is enabled or the application accepts BMP files for processing
-
Check for BMP file processing activityReview application logs, file access records, or network traffic for instances where BMP files have been opened, imported, or converted using the Drawings SDK.Affected if BMP files are being processed by the application using the vulnerable SDK component
-
Confirm SDK component versionIf your application bundles the ODA Drawings SDK, locate the specific ODA DLL files (typically named with patterns like OdBmp*, bmp*, or generic SDK binaries) and check their embedded version information.Affected if The bundled SDK component version is earlier than 2022.12
Your environment is affected if the Open Design Alliance Drawings SDK version is earlier than 2022.12 and your application processes BMP files using this SDK.
