Affected: AcademySoftwareFoundation MaterialX

MaterialX is an open standard for the exchange of rich material and look-development content across applications and renderers. In version 1.39.2, 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. An attacker could intentionally crash a target program that uses MaterialX by sending a malicious MTLX file. This is fixed in version 1.39.3.

Affected: PyPI: MaterialX

### Summary

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.

### Details

In `source/MaterialXCore/Material.cpp`, the following code extracts the output nodes for a given implementation graph:

```cpp InterfaceElementPtr impl = materialNodeDef->getImplementation(); if (impl && impl->isA<NodeGraph>()) { NodeGraphPtr implGraph = impl->asA<NodeGraph>(); for (OutputPtr defOutput : materialNodeDef->getOutputs()) { if (defOutput->getType() == MATERIAL_TYPE_STRING) { OutputPtr implGraphOutput = implGraph->getOutput(defOutput->getName()); for (GraphIterator it = implGraphOutput->traverseGraph().begin(); it != GraphIterator::end(); ++it) { ElementPtr upstreamElem = it.getUpstreamElement(); if (!upstreamElem) { it.setPruneSubgraph(true); continue; } NodePtr upstreamNode = upstreamElem->asA<Node>(); if (upstreamNode && upstream ```

However, when defining the `implGraphOutput` variable by getting the output node, the code doesn't check whether its value is null be…
