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.

2.  Impact Information

Background

Python is an interpreted, interactive, object-oriented, cross-platform programming language.

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Python users should update to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.3-r4"
