简介
远程 Oracle Linux 主机缺少安全更新。描述
远程 Oracle Linux 7 主机上安装的多个程序包受到 ELSA-2020-5720 公告中提及的一个漏洞影响。- 在低于 6.1.0 的 libvirt 4.10.0 - 6.x 版本中，发现 qemu/qemu_driver.c 的 qemuDomainGetStatsIOThread 中存在一个问题。当管理 QEMU 客户机时，发现负责检索域统计数据的 virDomainListGetStats libvirt API 中存在内存泄漏。建立只读连接的非特权用户可利用此缺陷，使用 domstats 命令导致内存泄漏，从而造成拒绝服务。(CVE-2020-12430)
请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
