概要
遠端 Oracle Linux 主機缺少安全性更新。說明
遠端 Oracle Linux 9 主機上安裝的套件受到 ELSA-2024-2236 公告中提及的一個弱點影響。- 在 libvirt 的 udevConnectListAllInterfaces() 函式中發現一個 NULL 指標解除參照瑕疵。當卸離主機介面，同時透過 virConnectListAllInterfaces API 收集介面清單時，可能會發生此問題。攻擊者可使用此瑕疵造成 libvirt 程序損毀，進而執行拒絕服務攻擊。(CVE-2024-2496)
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。
