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"
