<title>Python: Heap overflow in the included PCRE library</title>
<synopsis>
The "re" Python module is vulnerable to a heap overflow, possibly leading
to the execution of arbitrary code.

<affected>
<package name="dev-lang/python" auto="yes" arch="*">
<unaffected range="ge">2.3.5-r2</unaffected>
<vulnerable range="lt">2.3.5-r2</vulnerable>
</package>
</affected>
<background>
<p>
Python is an interpreted, interactive, object-oriented,
cross-platform programming language. The "re" Python module provides
regular expression functions.
</p>
</background>
<description>
<p>
The "re" Python module makes use of a private copy of libpcre
which is subject to an integer overflow leading to a heap overflow (see
GLSA 200508-17).
</p>
</description>
<impact type="normal">
<p>
An attacker could target a Python-based web application (or SUID
application) that would use untrusted data as regular expressions,
potentially resulting in the execution of arbitrary code (or privilege
escalation).
</p>
</impact>
<workaround>
<p>
Python users that don't run any Python web application or SUID
application (or that run one that wouldn't use untrusted inputs as
regular expressions) are not affected by this issue.
</p>
</workaround>
<resolution>
<p>
All Python users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/python-2.3.5-r2&quot;</code>
</resolution>
