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"
