简介
远程 Red Hat 主机缺少一个或多个安全更新。描述
远程 Redhat Enterprise Linux 8 主机上安装的多个程序包受到 RHSA-2022: 1764 公告中提及的多个漏洞的影响。- python：urllib：AbstractBasicAuthHandler 中的正则表达式 DoS (CVE-2021-3733)
- 在 python 中发现一个缺陷。python 的 HTTP 客户端代码中存在未正确处理的 HTTP 响应，因此可能允许控制 HTTP 服务器的远程攻击者使客户端脚本进入无限循环，从而消耗 CPU 时间。此漏洞最大的威胁在于系统可用性。(CVE-2021-3737)
- python-lxml：HTML Cleaner 允许通过构建的脚本和 SVG 嵌入式脚本 (CVE-2021-43818)
- python：urllib.parse 不会审查包含 ASCII 换行符和制表符的 URL (CVE-2022-0391)
请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。
