概要
遠端 Ubuntu 主機缺少一個或多個安全性更新。說明
遠端 Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS / Pro Realtime 22.04 LTS / Pro Realtime 24.04 LTS 主機上安裝的多個套件受到 USN-8744-1 公告中提及的多個弱點影響。據發現，Python 的 http.cookies 模組在某些 Cookie 操作中錯誤地處理了控制字元。攻擊者可能會利用此問題插入任意內容。此問題只影響 Ubuntu 14.04 LTS、Ubuntu 16.04 LTS、Ubuntu 18.04 LTS、Ubuntu 20.04 LTS、Ubuntu 22.04 LTS 和 Ubuntu 24.04。(CVE-2026-3644)
據發現，Python pyexpat 模組容易受到 Expat XML 剖析器中無限遞迴問題的影響。攻擊者可能利用此問題造成 Python 損毀，進而導致拒絕服務。此問題只影響 Ubuntu 14.04 LTS、Ubuntu 16.04 LTS、Ubuntu 18.04 LTS、Ubuntu 20.04 LTS、Ubuntu 22.04 LTS 和 Ubuntu 24.04。(CVE-2026-4224)
據發現，Python 的 tarfile 模組在擷取硬連結時沒有正確套用篩選參數。攻擊者可能會利用此問題，透過 filter='data' 繞過要求的限制，導致檔案以非預期的 uid 或 gid 擷取。(CVE-2026-4360)
據發現，Python 的 http.cookies 模組會錯誤地逸出 js_output() 方法中的值。
攻擊者可能會利用此問題插入任意 JavaScript 程式碼。(CVE-2026-6019)
據發現，Python 的 html.parser 模組錯誤地處理了重複的未終止標記宣告。攻擊者可能會利用此問題造成 Python 耗用過多 CPU 資源，進而導致拒絕服務。(CVE-2026-15308)
