CVE-2012-3519 Open this link in a new tabHow to fix?
Upgrade Debian:10 tor to version 0.2.3.20-rc-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.
routerlist.c in Tor before 0.2.2.38 uses a different amount of time for relay-list iteration depending on which relay is chosen, which might allow remote attackers to obtain sensitive information about relay selection via a timing side-channel attack.
