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>

<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.

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>

<resolution>
|
|
<p>
|
|
All Python 2.4 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=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 ">=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.
