CVE-2025-5169:
Linux Debian vulnerability analysis and mitigation
Overview
A vulnerability has been identified in Open Asset Import Library Assimp version 5.4.3, assigned CVE-2025-5169. The issue affects the MDLImporter::InternReadFile3DGSMDL345 function within the file assimp/code/AssetLib/MDL/MDLLoader.cpp. This vulnerability was discovered and disclosed on May 25, 2025, and is classified as an out-of-bounds read issue that requires local access to exploit (NVD, VulDB).
Technical details
The vulnerability is classified as an out-of-bounds read (CWE-125) issue, where the application reads data past the end or before the beginning of the intended buffer. The problem occurs specifically in the MDLImporter::InternReadFile3DGSMDL345 function when accessing pcFrames->type without proper boundary validation. The CVSS v3.1 base score is 3.3 (LOW) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L, while the CVSS v4.0 score is 4.8 (MEDIUM) (VulDB).
Impact
The vulnerability primarily impacts system availability. When exploited, it can lead to a heap buffer overflow condition, potentially causing application crashes or unstable behavior. The impact is considered relatively low due to the local access requirement and limited scope of the vulnerability (VulDB).
Mitigation and workarounds
Currently, there are no official fixes or mitigations available for this vulnerability. The project has decided to collect all Fuzzer bugs in a main issue to address them in the future. Users may consider replacing the affected component with an alternative product as a temporary workaround (VulDB).
