简介
远程 Oracle Linux 主机缺少一个或多个安全更新。描述
远程 Oracle Linux 8 主机上安装的程序包受到 ELSA-2020-4654 公告中提及的多个漏洞的影响。- Python 版 pip 程序包 19.2 之前版本在安装命令中指定 URL 时允许目录遍历，因为 Content-Disposition 标头在文件名中可以有 ../，这一点已由覆盖 /root/.ssh/authorized_keys 文件证实。这发生于 _download_http_url in _internal/download.py。
(CVE-2019-20916)
- 在 Python 3.8.3 及之前版本的 Lib/tarfile.py 中，由于 _proc_pax 缺少标头验证，因此攻击者可以构建一个由 tarfile.open 打开时产生无限循环的 TAR 归档文件。(CVE-2019-20907)
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。
