审计概述

对Vix-lang项目进行全面安全审计,发现110个问题,涵盖5大类别。

问题统计

等级 数量 说明
P0 8 立即修复 - 严重安全漏洞/逻辑错误
P1 28 24小时内 - 高危问题
P2 29 1周内 - 中危问题
P3 24 1个月内 - 低危问题

关键发现

P0 严重问题(需立即修复)

  1. SEC-001: 栈保护被禁用 -fno-stack-protector (CMakeLists.txt:128-129)
  2. SEC-002: install.sh中的命令注入 eval "$cmd" (src/install.sh:86)
  3. SEC-003: 栈缓冲区溢出 llvm_filename[256] (src/main.c:328-333)
  4. LOGIC-001: 使用未初始化的AST root (src/main.c:328-347)
  5. LOGIC-002: realloc返回值未检查 (10处)
  6. LOGIC-003: 空指针解引用风险 (src/ast/ast.c:557)
  7. LOGIC-004: strstr(NULL)崩溃 (src/main.c:330)
  8. BUILD-001: 缺少MSVC编译器支持

P1 高危问题(28个)

  • 安全漏洞: 整数溢出、TOCTOU竞态、堆耗尽等6个
  • 代码质量: 内存泄漏、除零错误、版本比较逻辑错误等7个
  • 文档问题: 13个断链、链接不一致、版本不同步等5个
  • 构建系统: 弃用API、无条件链接、打包错误等5个
  • 测试覆盖: CI不运行测试、标准库未测试等6个

按类别分布

类别 数量 占比
安全漏洞 20 18%
代码质量 24 22%
文档问题 15 14%
构建系统 16 15%
测试覆盖 18 16%

验证状态

  • 已验证: 22个(主要是文档问题)
  • 未验证: 88个(WSL环境依赖安装超时)

建议修复优先级

  1. 立即: 修复P0安全漏洞(栈保护、缓冲区溢出、命令注入)
  2. 24小时内: 修复P1内存问题和添加CI测试
  3. 1周内: 修复P2中危问题
  4. 1个月内: 代码清理和测试完善
