Уязвимость компонента Malformed File Handler кроссплатформенной библиотеки импорта 3D-моделей Assimp (Open Asset Import Library), позволяющая нарушителю вызвать отказ в обслуживании

Heap-based buffer overflow vulnerability in Assimp versions prior to 5.4.3 allows a local attacker to execute arbitrary code by importing a specially crafted file into the product.

A vulnerability, which was classified as critical, was found in Open Asset Import Library Assimp 5.4.3. Affected is the function Assimp::MD2Importer::InternReadFile in the library code/AssetLib/MD2/MD2Loader.cpp of the component Malformed File Handler. The manipulation of the argument Name leads to stack-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. It is recommended to upgrade the affected component.

A vulnerability was found in Open Asset Import Library Assimp 5.4.3 and classified as problematic. This issue affects the function MDLImporter::InternReadFile_Quake1 of the file assimp/code/AssetLib/MDL/MDLLoader.cpp. The manipulation leads to out-of-bounds read. 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.
