Synopsis
========
A buffer overflow in Python's "repr()" function can be exploited to
cause a Denial of Service and potentially allows the execution of
arbitrary code.
Background
==========
Python is an interpreted, interactive, object-oriented, cross-platform
programming language.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/python < 2.4.3-r4 >= 2.4.3-r4
*>= 2.3.5-r3
Description
===========
Benjamin C. Wiley Sittler discovered a buffer overflow in Python's
"repr()" function when handling UTF-32/UCS-4 encoded strings.
Impact
======
If a Python application processes attacker-supplied data with the
"repr()" function, this could potentially lead to the execution of
arbitrary code with the privileges of the affected application or a
Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Python users should update to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/2.4.3-r4"
