CVE-2026-0660: 
Autodesk 3ds Max vulnerability analysis and mitigation

CVE-2026-0660 is a Stack-Based Buffer Overflow vulnerability in Autodesk 3ds Max's GIF file parser (CWE-121) that allows arbitrary code execution when a maliciously crafted GIF file is opened. It affects Autodesk 3ds Max versions 2026 through versions prior to 2026.3.2. The vulnerability was published on February 4, 2026, with a patch made available shortly after. It carries a CVSS v3.1 base score of 8.4 (High) per NVD, or 7.8 (High) per ENISA/EUVD scoring (Autodesk Advisory, Red Hat CVE).

The root cause is a stack-based buffer overflow (CWE-121) triggered during the parsing of a specially crafted GIF image file within Autodesk 3ds Max. When the application processes the malformed GIF, insufficient bounds checking on stack-allocated buffers allows an attacker to overwrite adjacent memory, redirecting execution flow to attacker-controlled code. The attack vector is local, requiring the target user to open or import a malicious GIF file within 3ds Max. No public proof-of-concept exploit code has been identified at this time (Autodesk Advisory).

Successful exploitation allows an attacker to execute arbitrary code in the context of the Autodesk 3ds Max process, which runs with the privileges of the logged-in user. This can result in full compromise of the affected workstation, including unauthorized access to sensitive design files and intellectual property, modification or deletion of data, and disruption of application availability. Depending on the user's privilege level and network environment, lateral movement within the organization may also be possible (Autodesk Advisory, Red Hat CVE).

1. Craft malicious GIF: An attacker creates a specially crafted GIF file designed to trigger a stack-based buffer overflow in Autodesk 3ds Max's GIF parser, embedding a payload (e.g., shellcode or a reverse shell) within the malformed file structure.
2. Deliver the file: The attacker delivers the malicious GIF to a target user via phishing email, file-sharing platform, compromised website, or social engineering — targeting individuals known to use Autodesk 3ds Max (e.g., 3D artists, architects, game developers).
3. Trigger parsing: The victim opens or imports the GIF file within Autodesk 3ds Max, causing the application's GIF parser to process the malformed data.
4. Overflow the stack buffer: The parser fails to validate input size, causing a stack buffer overflow that overwrites the return address or control data on the stack with attacker-controlled values.
5. Execute arbitrary code: Execution is redirected to the attacker's payload, running arbitrary code in the context of the 3ds Max process with the victim user's privileges, enabling data theft, persistence, or further lateral movement (Autodesk Advisory).

• File System: Unexpected GIF files in user download directories, temp folders, or project directories that are unusually large or malformed; new executable files or scripts created in user-writable directories shortly after 3ds Max is used.
• Process: Unusual child processes spawned by the Autodesk 3ds Max process (e.g., cmd.exe, powershell.exe, curl, wget); 3ds Max crashing or terminating unexpectedly after opening a GIF file.
• Network: Unexpected outbound network connections originating from the 3ds Max process to unknown external IP addresses or domains, particularly after file open events.
• Logs: Application crash logs or Windows Event Log entries (Event ID 1000/1001) referencing Autodesk 3ds Max around the time a GIF file was opened; antivirus or EDR alerts triggered by 3ds Max process behavior.

Autodesk has released a patch in version 2026.3.2, which resolves this vulnerability. Users running Autodesk 3ds Max 2026 (any version prior to 2026.3.2) should upgrade immediately. As interim mitigations, users should avoid opening GIF files from untrusted or unknown sources within 3ds Max, implement application whitelisting, and conduct user awareness training on social engineering risks. Organizations should also monitor 3ds Max processes for anomalous behavior using endpoint detection and response (EDR) tools (Autodesk Advisory).
