CPython zipfile 模块高危漏洞 CVE-2024-8088 CPython 的 zipfile 模块存在一个高危漏洞，编号为 CVE-2024-8088。该漏洞会导致在处理恶意构造的 zip 档案时，程序陷入无限循环。具体来说，当使用 zipfile.Path 类及其方法（如 namelist()`、`iterdir()`、`extractall() 等）遍历 zip 档案条目名称时，可能会触发无限循环。 此漏洞的根本原因在于 zipfile._path._ancestry() 方法中的路径处理不当。具体来说，代码中的 path.rstrip(posixpath.sep) 和 while 循环条件未正确处理路径，导致无限循环。例如，`posixpath.split("//") 返回 ("//", "")，而 "//" != posixpath.sep` 导致循环无法退出。 该漏洞已被修复，建议更新 CPython 并加强输入验证，以防止潜在的拒绝服务攻击。 原文链接：https://www.openwall.com/lists/oss-security/2024/08/22/1https://www.openwall.com/lists/oss-security/2024/08/22/4 标签：#CPython#漏洞#zipfile#无限循环 #AIGC
