<p>
Python is an interpreted, interactive, object-oriented programming
language.

<description>
<p>
Multiple vulnerabilities were discovered in Python:
</p>
<ul>
<li>
David Remahl of Apple Product Security reported several integer
overflows in core modules such as stringobject, unicodeobject,
bufferobject, longobject, tupleobject, stropmodule, gcmodule,
mmapmodule (CVE-2008-2315).
</li>
<li>
David Remahl of Apple Product Security also reported an integer
overflow in the hashlib module, leading to unreliable cryptographic
digest results (CVE-2008-2316).
</li>
<li>
Justin Ferguson reported multiple buffer overflows in unicode string
processing that only affect 32bit systems (CVE-2008-3142).
</li>
<li>
The Google Security Team reported multiple integer overflows
(CVE-2008-3143).
</li>
<li>
Justin Ferguson reported multiple integer underflows and overflows in
the PyOS_vsnprintf() function, and an off-by-one error when passing
zero-length strings, leading to memory corruption (CVE-2008-3144).
</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could exploit these vulnerabilities in Python
applications or daemons that pass user-controlled input to vulnerable
functions. Exploitation might lead to the execution of arbitrary code
or a Denial of Service. Vulnerabilities within the hashlib might lead
to weakened cryptographic protection of data integrity or authenticity.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Python 2.4 users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.4.4-r14"</code>
<p>
All Python 2.5 users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.5.2-r6"</code>
<p>
Please note that Python 2.3 is masked since June 24, and we will not be
releasing updates to it. It will be removed from the tree in the near
future.
