NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
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.
