概要
遠端 Rocky Linux 主機缺少安全性更新。說明
遠端 Rocky Linux 9 主機已安裝受到 RLSA-2022:8003 公告中所提及一個弱點影響的套件。- 在 libvirt nwfilter 驅動程式中發現一個缺陷。virNWFilterObjListNumOfNWFilters 方法在反覆使用 virNWFilterObj 執行個體之前，無法取得「driver->nwfilters mutex」。沒有任何保護措施可阻止其他執行緒並行修改 driver->nwfilters 物件。此缺陷讓惡意的無權限使用者可透過 libvirt 的 API virConnectNumOfNWFilters 惡意利用此問題，以損毀網路篩選器管理程序 (libvirtd/virtnwfilterd)。(CVE-2022-0897)
請注意，Nessus 並未測試此問題，而是僅依據應用程式自我報告的版本號碼作出判斷。
