NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Debian.

This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
