Synopsis

遠端 NewStart CGSL 主機受到一個弱點影響。

描述

執行 CORE 5.04 / MAIN 5.04 版的遠端 NewStart CGSL 主機上安裝的 samba 套件受到一個弱點影響:

- 在 samba 中發現一個瑕疵。Samba smbd 檔案伺服器必須將 Windows 群組識別碼 (SID) 對應至 unix群組 ID (gids)。執行此動作的程式碼中有一個瑕疵,此瑕疵允許應用程式在負的快取項目已新增至對應快取時,讀取超出陣列結尾的資料。這可造成呼叫程式碼將這些值傳回至儲存使用者群組成員資格的處理程序 taoken。此弱點對資料機密性與完整性的威脅最大。
(CVE-2021-20254)

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。

解決方案

升級易受弱點影響的 CGSL samba 套件。請注意,可能尚未出爐已升級的套件。如需詳細資訊,請聯絡 ZTE。
