Synopsis
========

The "re" Python module is vulnerable to a heap overflow, possibly
leading to the execution of arbitrary code.

Background
==========

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

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/python < 2.3.5-r2 >= 2.3.5-r2

Description
===========

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
======

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).

Workaround
==========

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.

Resolution
==========

All Python users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.3.5-r2"
