Synopsis
========

Two vulnerabilities have been found in Tor, the worst of which can
allow remote attackers to cause a Denial of Service condition.

Background
==========

Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 net-misc/tor < 0.2.6.7 >= 0.2.6.7

Description
===========

Tor does not handle data correctly when specifically crafted data is
sent, and also fails to properly verify a descriptor provided by a
hidden service directory.

Impact
======

A remote attacker could cause a Denial of Service condition in both a
Tor client or a Tor server.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Tor users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=net-misc/tor-0.2.6.7”
