Описание
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.
A flaw was found in Mozilla Firefox and Thunderbird where null bytes were incorrectly parsed in HTML entities. This could lead to HTML comments being treated as code which could lead to XSS in a web application or HTML entities being masked from filters.
