概要
遠端 Red Hat 主機缺少 python39: 3.9/python39-devel: 3.9 的安全性更新。說明
遠端 Redhat Enterprise Linux 8 主機上安裝的套件受到 RHSA-2023: 6068 公告中提及的一個弱點影響。- 在 Python 3.8.18 之前的版本，3.9.18 之前的 3.9.x 版、3.10.13 之前的 3.10.x 版、3.11.5 之前的 3.11.x 版中發現一個問題。該弱點主要影響使用 TLS 用戶端驗證的伺服器 (例如 HTTP 伺服器)。如果建立了 TLS 伺服器端通訊端，將資料接收到通訊端緩衝區，然後快速關閉，則有一個短暫的視窗，SSLSocket 執行個體會將通訊端偵測為「未連線」，且不會發起交握，但攻擊者仍可從通訊端緩衝區讀取緩衝的資料。如果伺服器端 TLS 對等端預期收到用戶端憑證驗證，則此資料將不會經過驗證，且無法與有效的 TLS 資料流資料區別開來。資料大小限制為緩衝區可容納的數量。(TLS 連線無法直接用於資料洩漏，因為有弱點的程式碼路徑要求在 SSLSocket 初始化時關閉連線。) (CVE-2023-40217)
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。
解決方案
依據 RHSA-2023:6068 中的指引更新 RHEL python39: 3.9/python39-devel: 3.9 套件。另請參閱
