Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 Python 弱點 (USN-7951-1)

medium Nessus Plugin ID 284663

語言:

概要

遠端 Ubuntu 主機缺少安全性更新。

說明

遠端 Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 主機上安裝的多個套件受到 USN-7951-1 公告中提及的一個弱點影響。

據發現Python 的 http.client 未正確處理 HTTP 回應中的 Content-Length 標頭。惡意伺服器可惡意利用此弱點造成 Python 配置過量記憶體進而導致拒絕服務。

Tenable 已直接從 Ubuntu 安全公告擷取前置描述區塊。

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。
