CWE-188: Reliance on Data/Memory Layout
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product makes invalid assumptions about how protocol data or memory is organized at a lower level, resulting in unintended program behavior.
常见后果
影响范围: Integrity Confidentiality
技术影响: Modify Memory Read Memory
说明: Can result in unintended modifications or exposure of sensitive memory.
潜在缓解措施
阶段: Implementation Architecture and Design
描述: In flat address space situations, never allow computing memory addresses as offsets from another memory address.
阶段: Architecture and Design
描述: Fully specify protocol layout unambiguously, providing a structured grammar (e.g., a compilable yacc grammar).
阶段: Testing
描述: Testing: Test that the implementation properly handles each case in the protocol grammar.
检测方法
方法: Fuzzing
Fuzz testing (fuzzing) is a powerful technique for generating large numbers of diverse inputs - either randomly or algorithmically - and dynamically invoking the code with those inputs. Even with random inputs, it is often capable of generating unexpected results such as crashes, memory corruption, or resource consumption. Fuzzing effectively produces repeatable test cases that clearly indicate bugs, which helps developers to diagnose the issues.
