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.

When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
