USN-3391-1 fixed vulnerabilities in Firefox. The update introduced a performance regression with WebExtensions. This update fixes the problem.

We apologize for the inconvenience.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of Mozilla Firefox installed on the remote Windows host is prior to 55. It is, therefore, affected by multiple vulnerabilities, some of which allow code execution and potentially exploitable crashes.

The version of Mozilla Firefox installed on the remote macOS or Mac OS X host is prior to 55. It is, therefore, affected by multiple vulnerabilities, some of which allow code execution and potentially exploitable application crashes.
