medium Nessus Plugin ID 246614
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。- nfs處理解除鎖定路徑中的 nfs_get_lock_context 失敗記憶體不足時nfs_get_lock_context() 中的 nfs_lock_context 配置會失敗並傳回 -ENOMEM。如果我們錯誤地將 nfs4_unlockdata 結構 (其 l_ctx 成員已設定為 -ENOMEM) 視為有效並繼續執行 rpc_run_task()這將會在 nfs4_locku_prepare 中觸發 NULL 指標解除參照。例如錯誤
