Synopsis
=======

A flaw in Tor may allow the disclosure of arbitrary memory portions.



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 < 0.0.9.10 >= 0.0.9.10

Description
==========

A bug in Tor allows attackers to view arbitrary memory contents from an exit server's process space.

Impact
=====

A remote attacker could exploit the memory disclosure to gain sensitive information and possibly even private keys.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All Tor users should upgrade to the latest available version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.0.9.10"
