MaterialX Null Pointer Dereference in MaterialXCore Shader Generation due to Unchecked implGraphOutput
When parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files.
MaterialX Null Pointer Dereference in getShaderNodes due to Unchecked nodeGraph->getOutput return
When parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files.
MaterialX Lack of MTLX Import Depth Limit Leads to DoS (Denial-Of-Service) Via Stack Exhaustion
Nested imports of MaterialX files can lead to a crash via stack memory exhaustion, due to the lack of a limit on the "import chain" depth.
