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.

Python is an interpreted, interactive, object-oriented, cross-platform programming language.
Benjamin C. Wiley Sittler discovered a buffer overflow in Python's "repr()" function when handling UTF-32/UCS-4 encoded strings.
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.
There is no known workaround at this time.
All Python users should update to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.3-r4"
