概要
遠端 Oracle Linux 主機缺少安全性更新。說明
遠端 Oracle Linux 8 主機上安裝的套件受到 ELSA-2023-2860 公告中提及的一個弱點影響。- 在 Python 3.11.1 之前版本中發現一個問題。處理 IDNA (RFC 3490) 解碼器的部分輸入時，一個路徑中存在不必要的二次方演算法，如此一來，向解碼器顯示特製的過長名稱可導致 CPU 拒絕服務。主機名稱通常由遠端伺服器提供，而伺服器可能被惡意使用者控制，在這種情況下，他們可在嘗試使用攻擊者提供的假想主機名稱的用戶端上觸發 CPU 過度消耗。
例如，可以在狀態碼為 302 的 HTTP 回應的 Location 標頭中放置攻擊承載。計劃在 3.11.1、3.10.9、3.9.16、3.8.16 和 3.7.16 中進行修正。(CVE-2022-45061)
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作出判斷。
