An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

A weakness has been identified in Open Asset Import Library Assimp 17c12da. The affected element is the function Assimp::MDLImporter::ReadFaces_3DGS_MDL7 in the library code/AssetLib/LWO/LWOLoader.h of the component 3DGS MDL7 Model Parser. Executing a manipulation can lead to heap-based buffer overflow. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. This patch is called ee77bb09a42a49843ac85ef64c14d2328b251df1. Applying a patch is advised to resolve this issue.

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines until it ships, then apply the release.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
