How to fix?

Upgrade Debian:10 tor to version 0.2.1.29-1 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.

Heap-based buffer overflow in Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.
