Oracle Linux 8：python27：2.7 (ELSA-2020-4654)
high Nessus Plugin ID 180971
語言:
概要
遠端 Oracle Linux 主機缺少一個或多個安全性更新。說明
遠端 Oracle Linux 8 主機中安裝的套件受到 ELSA-2020-4654 公告中提及的多個弱點影響。- Python 的 pip 套件 19.2 之前版本在安裝命令中指定 URL 時會允許目錄遊走，這是因為 Content-Disposition 標頭的檔案名稱中可以包含 ../，覆寫 /root/.ssh/authorized_keys 檔案即為一例。此問題發生在 _internal/download.py 的 _download_http_url 中。
(CVE-2019-20916)
- 在 Python 3.8.3 及之前版本的 Lib/tarfile.py 中，由於 _proc_pax 缺少標頭驗證，攻擊者可以特製 TAR 封存，在 tarfile.open 開啟此封存時造成無限迴圈。(CVE-2019-20907)
請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。
