简介
远程 Oracle Linux 主机缺少安全更新。描述
远程 Oracle Linux 8 主机上安装的多个程序包受到 ELSA-2023-2860 公告中提及的漏洞的影响。- 在低于 3.11.1 版的 Python 中发现一个问题 。处理 IDNA (RFC 3490) 解码器的某些输入时，一个路径中存在不必要的二次算法，因此向解码器显示的特别构建的过长名称可导致 CPU 拒绝服务。主机名通常由可能受到恶意执行者控制的远程服务器提供；在这种情况下，它们可在尝试使用攻击者提供的假想主机名的客户端上触发过度消耗 CPU。
例如，攻击负载可放置在具有状态代码 302 的 HTTP 响应的 Location 标头中。计划在 3.11.1、 3.10.9、 3.9.16、 3.8.16 和 3.7.16 版中进行修复。(CVE-2022-45061)
请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
