    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"
