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

Affected Packages

Background

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

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
