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 write vulnerability exists when reading a TIF file using Open Design Alliance (ODA) Drawings Explorer before 2022.11. The specific issue exists after loading TIF files. Crafted data in a TIF file can trigger a write operation past the end of an allocated buffer. 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 · moderate confidence

An out-of-bounds write vulnerability exists in ODA Drawings Explorer versions prior to 2022.11 when parsing TIF image files. The vulnerability is triggered when processing crafted TIF file data that causes a write operation beyond the bounds of an allocated memory buffer, potentially allowing an attacker to achieve code execution in the context of the current process.

MitigationUpdate ODA Drawings Explorer to version 2022.11 or later to patch the vulnerability. Until patched, avoid opening untrusted or externally-sourced TIF files in the application.

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. Confirm ODA Drawings Explorer is installed
    Search the system for ODA Drawings Explorer executable or check typical installation directories such as Program Files or Program Files (x86). Look for files named DrawingsExplorer.exe or similar ODA application binaries.
    Affected if The application executable is found on the system.
  2. Determine the installed version
    Right-click the executable file, select Properties, and view the Details tab to find the Product Version. Alternatively, open the application and look for an About or Help menu item that displays version information.
    Affected if The reported version number is lower than 2022.11.
  3. Identify if TIF file handling is used
    Check if the application has processed any .tif or .tiff image files. Look in recent file open dialogs, recent documents lists, or the application's file history if available.
    Affected if TIF files have been opened or processed in the application.

A system is affected if ODA Drawings Explorer version 2022.11 or later is not installed AND the application is used to open TIF image files.
