概要

遠端 Red Hat 主機缺少一個或多個安全性更新。

說明

現已提供適用於 Red Hat Enterprise Linux 7 的 libreoffice 更新。Red Hat 產品安全性團隊已將此更新評等為具有中等安全性影響。可從〈參照〉一節的 CVE 連結中取得每個弱點之常見弱點評分系統 (CVSS) 的基本分數，其中包含有關嚴重性評等的詳細資訊。LibreOffice 是開放原始碼、由社群開發的辦公套件。其中包含主要桌面應用程式，如文書處理器、試算表、簡報管理員、公式編輯器和繪圖程式。LibreOffice 已取代 OpenOffice，提供類似但經過加強且延伸的辦公室套件。安全性修正：* 據發現，LibreOffice 會洩露在內嵌物件預覽中指定的檔案內容。攻擊者可利用此缺陷，透過特製文件，曝光以 LibreOffice 作為線上服務的系統的詳細資料。(CVE-2017-3157) 錯誤修正：* 以前，不當的資源管理方式會導致 LibreOffice Calc 試算表應用程式在關閉對話方塊視窗後 (啟用存取功能支援的情況下)，意外終止。我們已改善資源管理方式，所述問題因而不再發生。(BZ#1425536) * 以前，針對受密碼保護的文件輸入不正確的密碼時，系統會將該文件視為有效，然後嘗試執行後援作業，以便以純文字格式開啟該文件。因此，文件看似已順利載入，但卻只顯示已加密、無法讀取的內容。我們已做了修正，以在輸入不正確的密碼後終止匯入嘗試，現在，若輸入錯誤的密碼，系統不會載入任何文件。(BZ#1426348) * 以前，不當的資源管理方式會導致 LibreOffice Calc 試算表應用程式在結束時、關閉 CSV (逗號分隔值) 檔案的文字匯入對話方塊後 (啟用存取支援功能的情況下)，意外終止。我們已改善資源管理方式，所述問題因而不再發生。(BZ#1425535)
