Typestate-guided fuzzer for discovering use-after-free vulnerabilities

Haijun Wang, Xiaofei Xie, Yi Li, Cheng Wen, Yuekang Li, Yang Liu, Shengchao Qin, Hongxu Chen, Yulei Sui
2020 Proceedings of the ACM/IEEE 42nd International Conference on Software Engineering  
Our fuzzing process is then guided by the operation sequences in order to progressively generate test cases triggering property violations.  ...  To this end, we propose to model UaF vulnerabilities as typestate properties, and develop a typestateguided fuzzer, named UAFL, for discovering vulnerabilities violating typestate properties.  ...  For example, based on test case 'aaaseen', UAFL may generate a test case 'auaseen'.  ...

Classifier-Based Multi-atlas Label Propagation with Test-Specific Atlas Weighting for Correspondence-Free Scenarios [chapter]

Darko Zikic, Ben Glocker, Antonio Criminisi
2014 Lecture Notes in Computer Science  
To counteract the negative effects of the over-training property of AF for applications with highly heterogeneous examples, we employ test-specific atlas weighting by the STAPLE approach.  ...  This precludes its use for the large class of tasks without this property, such as tumor segmentation.  ...  We believe that in the light of growing annotated databases, the ability to learn from more similar data has the potential to provide increased accuracy, especially for under-represented outlier cases.  ...

Memory Management Test-Case Generation of C Programs Using Bounded Model Checking [chapter]

Herbert Rocha, Raimundo Barreto, Lucas Cordeiro
2015 Lecture Notes in Computer Science  
We describe a novel method to automatically generate and verify memory management test cases for unit tests, which are based on assertions extracted from safety properties typically generated by bounded  ...  In particular, the proposed method checks for properties related to pointer safety, memory leaks, and invalid deallocation.  ...  The proposed method generates automatically memory management test cases for structural unit tests, which are based on assertions from safety properties generated by BMC tools.  ...

The Subgraph Testing Model

Oded Goldreich, Dana Ron, Michael Wagner
2018 Innovations in Theoretical Computer Science  
We focus on bounded-degree base graphs and on the relation between testing graph properties in the subgraph model and testing the same properties in the bounded-degree graph model.  ...  We identify cases in which testing is significantly easier in one model than in the other as well as cases in which testing has approximately the same complexity in both models.  ...  General property testing as a special case of subgraph testing.  ...

The Diversity of Model Tuning Practices in Climate Science

Katie Steele, Charlotte Werndl
2016 Philosophy of Science  
We examine one example and show that, in employing classical hypothesis testing, it involves calibrating a base model against data that are also used to confirm the model.  ...  We argue, however, that aspects of the intuitive position are upheld by some methods, in particular, the general cross-validation method.  ...  In this case, hypothesis testing is not very telling-we are assured only of the long-run accuracy of the confidence interval for each base model, conditional on that base model being true.  ...
