Description Kurt Seifried 2011-12-23 02:40:57 UTC

Tor before 0.2.2.34, when configured as a bridge, sets up circuits
through a process different from the process used by a client, which
makes it easier for remote attackers to enumerate bridges by observing
circuit building.

Created tor tracking bugs for this issue

Affects: fedora-all [bug 771512]
Affects: epel-all [bug 771513]

Comment 2 Vincent Danen 2013-03-26 15:08:35 UTC

Current EPEL and Fedora provide 0.2.3.25 which includes this fix.
