CVE-2020-10593 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tor package and not the tor package as distributed by Debian.
Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.
