Linux Distros 未修補弱點：CVE-2024-2496
medium Nessus Plugin ID 227893
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- 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 依賴供應商報告的套件存在。
