### Summary 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. ### Details The MaterialX [specification](https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/documents/Specification/MaterialX.Specification.md#mtlx-file-format-definition) supports importing other files by using `XInclude` tags. When parsing file imports, recursion is used to process nested files in the form of a tree with the root node being the first MaterialX files parsed. However, there is no limit imposed to the depth of files that can be parsed by the library, therefore, by building a sufficiently deep chain of MaterialX files one referencing the next, it is possible to crash the process using the MaterialX library via stack exhaustion. ### PoC This test is going to employ Windows UNC paths, in order to make the Proof Of Concept more realistic. In fact, by using windows network shares, an attacker would be able t...
