CVE-2012-3519
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.

Does this matter?
Lower severity and a low EPSS score (2.42%). Track it; it rarely justifies an emergency change on its own.
