CVE-2012-3519

Publication date 26 August 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
