简介
远程 Rocky Linux 主机缺少一个或多个安全更新。描述
远程 Rocky Linux 8 主机上存在安装的程序包该程序包受到公告 RLSA-2021:1761 中提及的多个漏洞的影响。- 如果攻击者控制 HTTP 请求方法，则 Python 3.5.10 之前的 3.x、3.6.12 之前的 3.6.x、3.7.9 之前的 3.7.x 以及 3.8.5 之前的 3.8.x 中的 http.client 会允许 CRLF 注入，这一点已通过在 HTTPConnection.request 的第一个参数中插入 CR 和 LF 控制字符证实。(CVE-2020-26116)
- 如果攻击者控制 HTTP 请求方法，则 1.25.9 之前版本的 urllib3 会允许 CRLF 注入，这一点已通过在 putrequest() 的第一个参数中插入 CR 和 LF 控制字符证实。注意：此问题类似于 CVE-2020-26116。(CVE-2020-26137)
- 在 python-lxml 的清洁模块中发现 XSS 漏洞。模块的解析器未正确模拟浏览器，由此导致审查器和用户页面中的行为不同。远程攻击者可利用此缺陷运行任意 HTML/JS 代码。(CVE-2020-27783)
- Python 3.9.1 及之前的 3.x 版本可能受到 _ctypes/callproc.c 内的 PyCArg_repr 中缓冲区溢出的影响，这可导致在某些将浮点数接受为不受信任输入的 Python 应用程序中远程执行代码，c_double.from_param 的 1e300 参数即为一例。这是未安全使用 sprintf 所致。(CVE-2021-3177)
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。
