CVE-2025-2756

Name of the Vulnerable Software and Affected Versions Open Asset Import Library Assimp version 5.4.3

Description A critical issue has been found in the Open Asset Import Library Assimp. This issue affects the Assimp::AC3DImporter::ConvertObjectSection function in the AC3D File Handler component, specifically in the file code/AssetLib/AC/ACLoader.cpp. The manipulation of the tmp argument leads to a heap-based buffer overflow.

Restrict access to the AC3D File Handler component to minimize the risk of exploitation. Avoid using the tmp argument in the affected function until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
