1. 修復的CVE CVE-2018-10858 Samba是Samba團隊的一套可使UNIX系列的操作系統與微軟Windows操作系統的SMB/CIFS網絡協議做連結的自由軟件。該軟件支持共享打印機、互相傳輸資料文件等。 Samba 4.6.16之前版本、4.7.9之前版本和4.8.4之前版本中存在緩沖區錯誤漏洞。該漏洞源于網絡系統或產品在內存上執行操作時，未正確驗證數據邊界，導致向關聯的其他內存位置上執行了錯誤的讀寫操作。攻擊者可利用該漏洞導致緩沖區溢出或堆溢出等。 CVE-2018-10918 Samba是Samba團隊的一套可使UNIX系列的操作系統與微軟Windows操作系統的SMB/CIFS網絡協議做連結的自由軟件。該軟件支持共享打印機、互相傳輸資料文件等。 Samba中存在代碼問題漏洞。遠程攻擊者可利用該漏洞造成拒絕服務（Active Directory Domain Controller配置中的samba服務器崩潰）。 CVE-2018-10919 Samba是Samba團隊的一套可使UNIX系列的操作系統與微軟Windows操作系統的SMB/CIFS網絡協議做連結的自由軟件。該軟件支持共享打印機、互相傳輸資料文件等。Samba中存在信息泄露漏洞。該漏洞源于程序缺少訪問控制檢查。遠程攻擊者可借助LDAP搜索表達式利用該漏洞提取敏感的屬性值。 CVE-2018-1139 Samba是Samba團隊的一套可使UNIX系列的操作系統與微軟Windows操作系統的SMB/CIFS網絡協議做連結的自由軟件。該軟件支持共享打印機、互相傳輸資料文件等。 Samba 4.7.9之前版本和4.8.4之前版本中存在信任管理問題漏洞，該漏洞源于即使明確禁用了NTLMv1，程序依然允許使用弱的NTLMv1身份驗證。遠程攻擊者可利用該漏洞實施中間人攻擊，讀取samba服務器端和客戶端之間傳遞的憑證和其他的詳細信息。 2. 受影響的操作系統及軟件包 ·銀河麒麟桌面操作系統V4、銀河麒麟服務器操作系統V4 x86_64 架構：
