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 6 與 7 的更新版 libreoffice 套件，可修正多個安全性問題。

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。可針對每個弱點從〈參照〉一節的 CVE 連結中取得常見弱點評分系統 (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。

據發現，LibreOffice 並未正確地限制自動連結更新。透過誘騙受害者開啟特製的文件，攻擊者可能利用此瑕疵洩漏受害者能夠存取的檔案內容。(CVE-2015-4551)

據發現，存在一個剖析 PrinterSetup 資料時會導致堆積型緩衝區溢位的整數反向溢位瑕疵。透過誘騙使用者開啟特製的文件，攻擊者可能利用此瑕疵，藉由開啟檔案的使用者權限執行任意程式碼。(CVE-2015-5212)

在 LibreOffice 處理某些 Microsoft Word .doc 檔案的方式中，發現一個會造成堆積型緩衝區溢位的整數溢位瑕疵。透過誘騙使用者開啟特製的 Microsoft Word .doc 文件，攻擊者可能利用此瑕疵，以開啟檔案的使用者權限執行任意程式碼。(CVE-2015-5213)

據發現，LibreOffice 未對書籤索引正確地執行功能健全檢查。透過誘騙使用者開啟特製的文件，攻擊者可能利用此瑕疵，以開啟檔案的使用者權限執行任意程式碼。
(CVE-2015-5214)

建議所有 libreoffice 使用者皆升級至這些更新版套件，其中包含可更正這些問題的反向移植修補程式。

解決方案

更新受影響的套件。
