简介
远程 Red Hat 主机缺少一个或多个安全更新。描述
远程 Redhat Enterprise Linux 8 主机上安装的程序包受到 RHSA-2020: 4690 公告中提及的多个漏洞的影响。- qt：XML 实体扩展漏洞 (CVE-2015-9541)
- qt5-qtwebsockets: websocket 实现仅允许有限的帧和消息大小，因此攻击者可造成 DOS (CVE-2018-21035)
- qt：攻击者放置的文件可影响工作目录，并导致恶意代码执行（CVE-2020-0569、CVE-2020-0570）
- qt5: 在 OpenSSL 握手过程中，未正确调用 SSL_shutdown()，导致 TLS 应用程序拒绝服务 (CVE-2020-13962)
请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。
