Denial of service via out-of-bounds TIF read
Published Aug 6, 2026 · Updated Aug 6, 2026
Out-of-bounds reads in Autodesk AutoCAD, AutoCAD LT, and Revit allow attackers to cause denial of service by importing a crafted TIF file. The image handling library reads beyond an allocated buffer while parsing the TIF during image import; Autodesk has not identified the parser routine or malformed field. Exploitation requires user interaction to import the file, and Autodesk reports denial of service without code execution for this CVE.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2024.0.0 <2024.3.5
- Affected versionversion=2026.0.0 <2026.5.0
- Affected versionversion=2027.0.0 <2027.1.0
