Code Duplication on Stack Overflow [article]

Sebastian Baltes, Christoph Treude
2020 pre-print
Despite the unarguable importance of Stack Overflow (SO) for the daily work of many software developers and despite existing knowledge about the impact of code duplication on software maintainability,  ...  In this paper, we motivate why studies on code duplication within SO are needed and how existing studies on code reuse differ from this new research direction.  ...  We outlined the two cases presented in Sections 2.1 and 2.2 using examples from our preliminary analysis and asked the community: How to handle code clones on Stack Overflow?  ...

Stack Memory Buffer Overflow Protection based on Duplication and Randomization

Sahel Alouneh, Mazen Kharbutli, Rana AlQurem
2013 Procedia Computer Science  
The results of our implementation show high protection against integer overflow and buffer overflow attacks.  ...  Vulnerabilities in the program's stack are commonly exploited by attackers in the form of stack-based attacks.  ...  Mainly, our solution depends on duplication and randomization of the new stack locations where the return addresses will be stored and checked.  ...

Using faults for buffer overflow effects

Pierre-Alain Fouque, Delphine Leresteux, Frédéric Valette
2012 Proceedings of the 27th Annual ACM Symposium on Applied Computing - SAC '12  
In this short paper, we demonstrate by using one example that countermeasures against buffer overflow must also be used for software running on embedded processors.  ...  Here, we show that they can be exploited to make more damage, taking the control of a machine as buffer overflow attacks do for instance.  ...  Second countermeasure duplicates stack pointer in a variable, in a register, in other part of the stack or in another duplicated stack like Stack Shield [2] .  ...
