Synopsis

遠端 Red Hat 主機缺少一個或多個安全性更新。

描述

現已提供適用於 Red Hat Enterprise Linux 4 Extras、Red Hat Enterprise Linux 5 和 6 Supplementary 的更新版 acroread 套件,可修正多個安全性問題。

Red Hat 安全性回應團隊已將此更新評為具有重大安全性影響。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。

Adobe Reader 可讓使用者檢視和列印可攜式文件格式 (Portable Document Format, PDF) 的文件。

此更新將修正 Adobe Reader 中的多個安全性瑕疵。這些瑕疵於 Adobe 安全性頁面 APSB11-24 中詳述,列在<參照>一節中。特製的 PDF 檔案可導致 Adobe Reader 當機,或可能在開啟時以執行 Adobe Reader 的使用者身分執行任意程式碼。(CVE-2011-2431、CVE-2011-2432、CVE-2011-2433、CVE-2011-2434、CVE-2011-2435、CVE-2011-2436、CVE-2011-2437、CVE-2011-2438、CVE-2011-2439、CVE-2011-2440、CVE-2011-2442)

此更新也可修正 Adobe Reader 中內嵌的 Adobe Flash Player 之多個安全性瑕疵。Adobe 安全性頁面 APSB11-21 和 APSB11-26 會詳細說明這些瑕疵,如<參照>一節中所列。

含有內嵌特製 SWF 檔案的 PDF 檔案可造成 Adobe Reader 當機,或可能在開啟時以執行 Adobe Reader 的使用者身分執行任意程式碼。(CVE-2011-2130、CVE-2011-2134、CVE-2011-2135、CVE-2011-2136、CVE-2011-2137、CVE-2011-2138、CVE-2011-2139、CVE-2011-2140、CVE-2011-2414、CVE-2011-2415、CVE-2011-2416、CVE-2011-2417、CVE-2011-2424、CVE-2011-2425、CVE-2011-2426、CVE-2011-2427、CVE-2011-2428、CVE-2011-2430)

Adobe Flash Player 中的一個瑕疵可允許攻擊者誘騙受害者造訪特製網頁,藉此發動跨網站指令碼 (XSS) 攻擊。(CVE-2011-2444)

此更新也可修正 Adobe Flash Player 中的一個資訊洩漏瑕疵。(CVE-2011-2429)

所有 Adobe Reader 使用者皆應安裝這些更新版套件。這其中包含 Adobe Reader 9.4.6 版,此版本不容易發生這些問題。所有執行中的 Adobe Reader 執行個體都必須重新啟動,更新才會生效。

解決方案

更新受影響的 acroread 和/或 acroread-plugin 套件。
