<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.

Python is an interpreted, interactive, object-oriented,
|
|
cross-platform programming language. The "re" Python module provides
|
|
regular expression functions.
|
|

|
<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).
|
|

<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 ">=dev-lang/python-2.3.5-r2"</code>
|
|
