CVE-2019-11763

Priority
Description
Failure to correctly handle null bytes when processing HTML entities
resulted in Firefox incorrectly parsing these entities. This could have led
to HTML comment text being treated as HTML which could have led to XSS in a
web application under certain conditions. It could have also led to HTML
entities being masked from filters - enabling the use of entities to mask
the actual characters of interest from filters. This vulnerability affects
Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
