FreeBSD: VID-05463e0a-abd3-4fa4-bd5f-cd5ed132d4c6 (CVE-2019-11744): mozilla -- multiple vulnerabilities

Some HTML elements, such as andlt;titleandgt; and andlt;textareaandgt;, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. This vulnerability affects Firefox less than 69, Thunderbird less than 68.1, Thunderbird less than 60.9, Firefox ESR less than 60.9, and Firefox ESR less than 68.1.
