FreeBSD: VID-cd81806c-26e7-4d4a-8425-02724a2f48af (CVE-2018-12368): mozilla -- multiple vulnerabilities

Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the "Mark of the Web." Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems. *Note: this issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird less than 60, Thunderbird less than 52.9, Firefox ESR less than 60.1, Firefox ESR less than 52.9, and Firefox less than 61.
