概要
遠端 Rocky Linux 主機缺少安全性更新。說明
遠端 Rocky Linux 8 主機已安裝受 RLSA-2022:0332 公告中提及的一個弱點影響的套件。- Samba vfs_fruit 模組使用延伸檔案屬性 (EA、xattr) 提供與 Apple SMB 用戶端的增強相容性，以及與 Netatalk 3 AFP 檔案伺服器的互通性。已設定 vfs_fruit 的 Samba 4.13.17、 4.14.12 和 4.15.5 更早版本允許透過特製的延伸檔案屬性進行超出邊界堆積讀取和寫入。具有延伸檔案屬性寫入存取權的遠端攻擊者可以 smbd 權限 (通常是 root 權限) 執行任意程式碼。(CVE-2021-44142)
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。
