VulSCC: image-based vulnerability detection with SPP-CNN and code large language model

Abstract Deep learning excels in detecting source code vulnerabilities, where image-based detection methods overcome ignoring deep code semantic information in token-based methods and the inefficiency of graph-based methods. Unfortunately, current image-based methods cannot sufficiently extract vulnerability-related features due to three key limitations: (1) the inappropriateness of the construction of node centrality for sequential Program Dependency Graphs (PDGs), (2) the ineffective code anal
