<affected>
<package name="dev-lang/python" auto="yes" arch="*">
<unaffected range="ge">2.2.2</unaffected>
<unaffected range="lt">2.2</unaffected>
<vulnerable range="lt">2.2.2</vulnerable>
</package>

<background>
<p>
Python is an interpreted, interactive, object-oriented, cross-platform
programming language.
</p>
</background>
<description>
<p>
If IPV6 is disabled in Python 2.2, getaddrinfo() is not able to handle IPV6
DNS requests properly and a buffer overflow occurs.
</p>
</description>
<impact type="high">
<p>
An attacker can execute arbitrary code as the user running python.
</p>
</impact>
<workaround>
<p>
Users with IPV6 enabled are not affected by this vulnerability.
</p>
</workaround>
<resolution>
<p>
All Python 2.2 users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=dev-lang/python-2.2.2"
# emerge ">=dev-lang/python-2.2.2"</code>
</resolution>
