How to fix?

Upgrade Echo:latest thunderbird to version 1:102.9.0-1 or higher.

NVD Description

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

When accessing throttled streams, the count of available bytes needed to be checked in the calling function to be within bounds. This may have lead future code to be incorrect and vulnerable. This vulnerability affects Firefox < 111, Firefox ESR < 102.9, and Thunderbird < 102.9.
