Oracle Linux 7：libvirt (ELSA-2020-4000)
medium Nessus 插件 ID 180904
语言：
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 7 主机上安装的多个程序包受到 ELSA-2020-4000 公告中提及的多个漏洞影响。- 6.0.0 之前的 libvirt 中的 qemu/qemu_driver.c 未能在向客户机查询期间正确处理监控作业，这让攻击者造成拒绝服务（API 阻止）。(CVE-2019-20485)
- 在上游版本 3.10.0 引入的 libvirt API 中发现一个空指针取消参考漏洞，该漏洞已在 libvirt 6.0.0 中修复，以便基于其目标路径获取存储池。更详细地讲，此缺陷会影响在没有目标路径的情况下创建的存储池，例如 gluster 和 RBD 等基于网络的池。
具有只读连接的非特权用户可利用此缺陷，导致 libvirt 后台程序崩溃，从而可能造成拒绝服务。(CVE-2020-10703)
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。
