简介
远程 Oracle Linux 主机缺少安全更新。描述
远程 Oracle Linux 7 主机上安装的程序包受到 ELSA-2020-5961 公告中提及的漏洞的影响。- 在 6.8.0 之前的版本中，在负责请求运行 QEMU 域的网络界面有关信息的 libvirt API 中发现一个双重释放内存问题。此缺陷会影响 polkit 访问控制驱动程序。具体而言，以有限的 ACL 权限连接到读写套接字的客户机可利用此缺陷使 libvirt 后台程序崩溃，从而导致拒绝服务或可能升级其在系统上的权限。此漏洞最大的威胁在于数据机密性和完整性，以及系统可用性。(CVE-2020-25637)
请注意，Nessus 尚未测试此问题，而是只依赖于应用程序自我报告的版本号。
