RHEL 8:python27:2.7 (RHSA-2023: 7042)

medium Nessus Plugin ID 185661

概要

遠端 Red Hat 主機缺少安全性更新。

說明

遠端 Redhat Enterprise Linux 8 主機上安裝的套件受到 RHSA-2023: 7042 公告中提及的一個弱點影響。

- Requests 是一個 HTTP 程式庫。自 Requests 2.3.0 起,Requests 重新導向至 HTTPS 端點時會向目的地伺服器洩漏 Proxy-Authorization 標頭。這是我們使用 `rebuild_proxies` 將 `Proxy-Authorization` 標頭重新附加到要求的結果。對於透過通道傳送的 HTTP 連線,Proxy 會識別要求本身中的標頭,並在轉送至目的地伺服器之前將其移除。但在透過 HTTPS 傳送時,因為 Proxy 無法檢視通道要求,因而必須在 CONNECT 要求中傳送「Proxy-Authorization」標頭。這會導致 Requests 意外將 Proxy 憑證轉送至目的地伺服器,進而允許惡意執行者洩漏敏感資訊。此問題已在 2.31.0 版中修正。
(CVE-2023-32681)

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

更新受影響的套件。
