How to fix?

Upgrade Ubuntu:20.04 firefox to version 133.0+build2-0ubuntu0.20.04.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

NSC_DeriveKey inadvertently assumed that the phKey parameter is always non-NULL. When it was passed as NULL, a segmentation fault (SEGV) occurred, leading to crashes. This behavior conflicted with the PKCS#11 v3.0 specification, which allows phKey to be NULL for certain mechanisms. This vulnerability affects Firefox < 133 and Thunderbird < 133.
