Runtime Countermeasures for Code Injection Attacks Against C and C++ Programs

摘要

The lack of memory safety in C/C++ often leads to vulnerabilities. Code injection attacks exploit these vulnerabilities to gain control over the execution flow of applications. These attacks have played a key role in many major security incidents. Consequently, a huge body of research on countermeasures exists. We provide a comprehensive and structured survey of vulnerabilities and countermeasures that operate at runtime. These countermeasures make different trade-offs in terms of performance, effectivity, compatibility, etc., making it hard to evaluate and compare countermeasures in a given context. We define a classification and evaluation framework on the basis of which countermeasures can be assessed.
