PostgreSQL quote.c 特殊浮点值处理漏洞修复分析

漏洞概述 该网页截图展示了一个关于数据库处理中特殊浮点值（如“infinity”）的漏洞修复。主要问题在于 文件中的 函数未能正确处理这些特殊浮点值，导致潜在的安全风险。 影响范围 影响模块： 文件中的 函数。 影响类型：特殊浮点值（如“infinity”）的处理不当。 潜在风险：可能导致数据注入或其他安全漏洞。 修复方案 1. 移除几何特定函数：将 中的几何特定函数移至 。 2. 重命名函数：将 重命名为 。 3. 标准化错误消息：统一错误消息格式。 POC代码/利用代码 以下是修复前后的代码对比： 修复前 ```c char quote_string(PGconn conn, const char string, size_t len, size_t retlen, int encoding);
