简介
远程 Rocky Linux 主机缺少安全更新。描述
远程 Rocky Linux 9 主机上存在安装的程序包该程序包受到公告 RLSA-2022:8003 中提及的漏洞的影响。- 在 libvirt nwfilter 驱动程序中发现一个缺陷。在迭代 virNWFilterObj 实例之前，virNWFilterObjListNumOfNWFilters 方法无法获取 driver->nwfilters 互斥体。没有保护机制可以阻止其他线程并行修改 driver->nwfilters 对象。此缺陷允许恶意的无特权用户通过 libvirt 的 API virConnectNumOfNWFilters 利用此问题，从而使网络过滤器管理后台程序 (libvirtd/virtnwfilterd) 崩溃。(CVE-2022-0897)
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。
