NVD Description

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

Mozilla developers and community members reported memory safety bugs present in Firefox 75. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 76.
