When parsing an MTLX file with multiple nested nodegraph implementations, the MaterialX XML parsing logic can potentially crash due to stack exhaustion.
By specification, multiple kinds of elements in MTLX support nesting other elements, such as in the case of nodegraph elements. Parsing these subtrees is implemented via recursion, and since there is no max depth imposed on the XML document, this can lead to a stack overflow when the library parses an MTLX file with an excessively high number of nested elements.
Please download the recursion_overflow.mtlx file from the following link:

build/bin/MaterialXView --material recursion_overflow.mtlx
An attacker could intentionally crash a target program that uses MaterialX by sending a malicious MTLX file.
