|
Multiple vulnerabilities were discovered in Python:
|
|
</p>
|
|
<ul>
|
|
<li>David
|
|
Remahl reported multiple integer overflows in the file imageop.c,
|
|
leading to a heap-based buffer overflow (CVE-2008-1679). This issue is
|
|
due to an incomplete fix for CVE-2007-4965.</li>
|
|
<li>Justin Ferguson
|
|
discovered that an integer signedness error in the zlib extension
|
|
module might trigger insufficient memory allocation and a buffer
|
|
overflow via a negative signed integer (CVE-2008-1721).</li>
|
|
<li>Justin
|
|
Ferguson discovered that insufficient input validation in the
|
|
PyString_FromStringAndSize() function might lead to a buffer overflow
|
|
(CVE-2008-1887).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could exploit these vulnerabilities to cause a Denial
|
|
of Service or possibly the remote execution of arbitrary code with the
|
|
privileges of the user running Python.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
The imageop module is no longer built in the unaffected versions.

All Python 2.3 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.3.6-r6"</code>
|
|
<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-r13"</code>
|
