HDF5 HST_conv_struct Use-after-Free 漏洞分析

漏洞总结：HST_conv_struct Use after Free 漏洞概述 HDF5 库中的 函数存在堆释放后使用（Use-after-Free）漏洞。攻击者可以通过控制 HDF5 文件中的 字段，在解析文件时触发该漏洞。这可能导致拒绝服务（DoS），在特定条件下可能进一步导致远程代码执行（RCE）。该漏洞是通过模糊测试 辅助工具发现的。 影响范围 受影响版本: 修复版本: None (截图中显示暂无官方补丁) 修复方案 目前截图中显示无官方修复版本。建议用户关注官方更新或自行编译修复后的版本。 POC 代码 1. 编译环境配置 2. 利用代码及 ASAN 输出 ASAN 报错关键信息： ```text HDF5/DUMP: Error in H5T_conv_struct(): heap-use-after-free on address 0x7fa4bebc4 at 0x7fa4bebc541 at 0x7ff00b02649 READ of size 3529 at 0x7fa4bebc4 thread T0 ...
