- Summary
- ONNX: Null Pointer Dereference in Upsample Version Converter Adapter (Zero Inputs)
- Details
-
Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. From 1.9.0 before 1.22.0, onnx.versionconverter.convertversion() can dereference a null pointer in Upsample67::adaptupsample67() in onnx/versionconverter/adapters/upsample67.h when processing an untrusted model with an Upsample node that has zero inputs, causing an unrecoverable denial of service. This issue is fixed in version 1.22.0.
