high Nessus Plugin ID 142445
語系：
概要
遠端 Red Hat 主機缺少一個或多個安全性更新。說明
遠端 Redhat Enterprise Linux 8 主機上安裝的套件受到 RHSA-2020: 4690 公告中所提及的多個弱點影響。- qt：XML 實體擴充弱點 (CVE-2015-9541)
- qt5-qtwebsockets：websocket 實作僅允許有限的框架和訊息大小，因此攻擊者可造成 DOS (CVE-2018-21035)
- qt：攻擊者放置的檔案可影響工作目錄並導致惡意程式碼執行 (CVE-2020-0569、CVE-2020-0570)
- qt5：在 TLS 應用程式中不正確地呼叫 OpenSSL mid-handshake 的 SSL_shutdown()，可造成拒絕服務 (CVE-2020-13962)
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。
