How to fix?

Upgrade Debian:10 tor to version 0.2.2.27-beta-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tor package and not the tor package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

Tor before 0.2.2.25-alpha, when configured as a relay without the Nickname configuration option, uses the local hostname as the Nickname value, which allows remote attackers to obtain potentially sensitive information by reading this value.
