概要
遠端 Debian 主機上缺少一個或多個安全性更新。說明
遠端 Debian 9 主機上安裝的多個套件受 dla-2782 公告中提及的多個弱點影響。- Mozilla 開發人員報告，Firefox 92 和 Firefox ESR 91.1 中存在記憶體安全性錯誤。某些錯誤顯示記憶體會遭到損毀，我們推測若有心人士有意操控，可能惡意利用其中部分錯誤執行任意程式碼。此弱點會影響 Thunderbird < 78.15、Thunderbird < 91.2、Firefox ESR < 91.2、Firefox ESR < 78.15 和 Firefox < 93。(CVE-2021-38500)
- 在 MessageTasks 上作業期間，工作可能已在排程時遭到移除，進而導致記憶體損毀以及可能引致惡意當機。此弱點會影響 Thunderbird < 78.15、Thunderbird < 91.2、Firefox ESR < 91.2、Firefox ESR < 78.15 和 Firefox < 93。(CVE-2021-38496)
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 firefox-esr 套件。針對 Debian 9「Stretch」，已在 78.15.0esr-1~deb9u1 版本中修正這些問題。
