released-security-patches

Tor before 0.2.2.34, when configured as a bridge, uses direct DirPort
access instead of a Tor TLS connection for a directory fetch, which
makes it easier for remote attackers to enumerate bridges by observing
DirPort connections.

Current EPEL and Fedora provide 0.2.3.25 which includes this fix.
