CVE-2014-5117 Open this link in a new tabHow to fix?
Upgrade Debian:10 tor to version 0.2.4.23-1 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 0.2.4.23 and 0.2.5 before 0.2.5.6-alpha maintains a circuit after an inbound RELAY_EARLY cell is received by a client, which makes it easier for remote attackers to conduct traffic-confirmation attacks by using the pattern of RELAY and RELAY_EARLY cells as a means of communicating information about hidden service names.
