CVE-2018-0490 Open this link in a new tabHow to fix?
Upgrade Debian:10 tor to version 0.3.2.10-1 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.
An issue was discovered in Tor before 0.2.9.15, 0.3.1.x before 0.3.1.10, and 0.3.2.x before 0.3.2.10. The directory-authority protocol-list subprotocol implementation allows remote attackers to cause a denial of service (NULL pointer dereference and directory-authority crash) via a misformatted relay descriptor that is mishandled during voting.
