远程 macOS 或 Mac OS X 主机上安装的 Mozilla Firefox 版本低于 55。因而会受到多个漏洞的影响，其中一些漏洞允许代码执行，并可能导致可遭利用的应用程序崩溃。

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3391-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to conduct cross-site scripting (XSS)     attacks, bypass sandbox restrictions, obtain sensitive information, spoof the origin of modal alerts,     bypass same origin restrictions, read uninitialized memory, cause a denial of service via program crash or     hang, or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779, CVE-2017-7780, CVE-2017-7781,     CVE-2017-7783, CVE-2017-7784, CVE-2017-7785, CVE-2017-7786, CVE-2017-7787, CVE-2017-7788, CVE-2017-7789,     CVE-2017-7791, CVE-2017-7792, CVE-2017-7794, CVE-2017-7797, CVE-2017-7798, CVE-2017-7799, CVE-2017-7800,     CVE-2017-7801, CVE-2017-7802, CVE-2017-7803, CVE-2017-7806, CVE-2017-7807, CVE-2017-7808, CVE-2017-7809)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
