dc.description.resumoIn the last three decades, memory safety issues in low-level programming languages such as C or C++ have been one of the significant sources of security vulnerabilities; however, there exist only a few attempts with limited success to cope with the complexity of C++ program verification. This work describes and evaluates a novel verification approach based on bounded model checking (BMC) and satisfiability modulo theories (SMT) to verify C++ programs formally. This verification approach analyzes bounded C++ programs by encoding various sophisticated features that the C++ programming language offers into SMT, such as templates, sequential and associative containers, inheritance, polymorphism, and exception handling. We formalize these sophisticated features within our formal verification framework using a decidable fragment of first-order logic and then show how state-of-the-art SMT solvers can efficiently handle that. We implemented this verification approach on top of the Efficient SMT-Based Context-Bounded Model Checker (ESBMC). We compare ESBMC to LLBMC and DIVINE, which are state-of-the-art verifiers to check C++ programs directly from LLVM bitcode. The experimental evaluation contains a set of over 1,500 benchmarks from several sources (e.g., Deitel & Deitel, NEC Corporation, and GCC test suite), which covers several C++ features. Experimental results show that ESBMC can handle a wide range of C++ programs, presenting a higher number of correct verification results, and at the same time, it reduces the verification time if compared to LLBMC and DIVINE tools.por
dc.description.abstractEste trabalho descreve e avalia o Efficient SMT-Based Context-Bounded Model Checker (ESBMC) para verificar formalmente programas C++. O ESBMC implementa a técnica de verificação de modelos limitados (do inglês, bounded model checking -- BMC) com base em teorias do módulo da satisfabilidade (do inglês, satisfiability modulo theories -- SMT) para lidar com recursos complexos que a linguagem de programação C++ oferece, tais como templates, contêineres sequenciais e associativos, herança, polimorfismo e manipulação de exceções. ESBMC é comparado as ferramentas LLBMC e DIVINE, as quais verificam os programas C++ diretamente a nível de bitcode do LLVM. Resultados experimentais mostram que o ESBMC pode lidar com uma ampla gama de estruturas do C++, apresentando uma taxa de aproximadamente 85% de verificações corretas e, ao mesmo tempo, reduzindo o tempo de verificação se comparado as ferramentas LLBMC e DIVINE.por
