CVE-2025-5204

Estado: AnalizadaMedia (4.8)—

A vulnerability classified as problematic has been found in Open Asset Import Library Assimp 5.4.3. This affects the function MDLImporter::ParseSkinLump_3DGS_MDL7 of the file assimp/code/AssetLib/MDL/MDLMaterialLoader.cpp. The manipulation leads to out-of-bounds read. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The project decided to collect all Fuzzer bugs in a main-issue to address them in the future.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
