CVE-2021-44859
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 when reading a TGA file using Open Design Alliance Drawings SDK before 2022.12. The specific issue exists after loading TGA files. An unchecked input data from a crafted TGA file leads to an out-of-bounds read. 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 confidenceAn out-of-bounds read vulnerability exists in Open Design Alliance Drawings SDK versions prior to 2022.12 when processing TGA (Targa) image files. The vulnerability stems from insufficient validation of input data from crafted TGA files, allowing an attacker to read beyond allocated memory boundaries and potentially achieve code execution 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.
-
Locate Open Design Alliance Drawings SDK installationSearch for files named 'ODA' or 'Oda' in program directories, or look for DLLs with 'oda' or 'Od' prefixes in application bin folders. Check the application's dependencies or manifest files that reference ODA components.Affected if The SDK is present on the system
-
Determine installed SDK versionRight-click any ODA DLL file (commonly named OdDwgX.dll, OdDbX.dll, or similar) and view Properties > Details to read the File Version. Alternatively, check the application's documentation or bundled third-party components list.Affected if The version is lower than 2022.12
-
Verify TGA image processing capability is in useInspect the application configuration or code that uses the Drawings SDK to determine if TGA file import or rendering features are enabled. Check for file type handlers or plug-ins registered for '.tga' extension.Affected if TGA file processing is enabled or the application handles TGA files
-
Check for recent file processing activity involving TGA filesReview application logs, file access logs, or temporary directories for evidence of recently processed .tga files. Use file system monitoring tools to identify if any TGA files have been opened.Affected if The system has recently processed untrusted TGA files
The system is affected if Open Design Alliance Drawings SDK version below 2022.12 is installed AND TGA image files are processed by an application using this SDK.

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.
dbcve · scoped2022.12
Update Drawings SDK to version 2022.12 or later to obtain the patch for this vulnerability. Until the update is applied, avoid processing untrusted TGA files with affected SDK versions.
Drawings SDK 2022.12 or later
- Identify the current version of Open Design Alliance Drawings SDK being used in your application
- Download Drawings SDK version 2022.12 or later from www.opendesign.com
- Follow the vendor's upgrade documentation to integrate the new SDK version into your project
- Rebuild your application with the updated SDK
- Redeploy the rebuilt application to verify the vulnerability is resolved
