CVE-2025-6120

Estado: AnalizadaBaja (1.9)—

A vulnerability classified as critical was found in Open Asset Import Library Assimp up to 5.4.3. Affected by this vulnerability is the function read_meshes in the library assimp/code/AssetLib/MDL/HalfLife/HL1MDLLoader.cpp. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. 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).
