Linux Distros 未修補的弱點：CVE-2024-4418
medium Nessus Plugin ID 229367
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 中發現導致堆疊釋放後使用瑕疵的爭用情形。由於 virNetClientIOEventLoop() 方法中的錯誤假設堆疊配置的 virNetClientIOEventData 結構的 `data` 指標最終會在 virNetClientIOEventFD 回呼中使用而當從 virNetClientIOEventLoop() 傳回時同時釋放資料指標的堆疊框架時該指標的堆疊框架會出現。「virtproxyd」程序可用來觸發要求。如果 libvirt 設定了精細的存取控制則此問題理論上會允許使用者逸出其原本受限的存取權。此瑕疵允許無權限的本機使用者不經驗證即存取 virtproxyd。遠端使用者需要先驗證才能存取。 (CVE-2024-4418)
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
