    Synopsis
    ========

    Python 2.2 has a vulnerability in DNS handling when IPV6 is disabled
    and a malformed IPV6 address is encountered by getaddrinfo().

    Background
    ==========

    Python is an interpreted, interactive, object-oriented, cross-platform
    programming language.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-lang/python < 2.2.2 >= 2.2.2
                                                                     < 2.2

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

    If IPV6 is disabled in Python 2.2, getaddrinfo() is not able to handle
    IPV6 DNS requests properly and a buffer overflow occurs.

    Impact
    ======

    An attacker can execute arbitrary code as the user running python.

    Workaround
    ==========

    Users with IPV6 enabled are not affected by this vulnerability.

    Resolution
    ==========

    All Python 2.2 users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=dev-lang/python-2.2.2"
        # emerge ">=dev-lang/python-2.2.2"
