Synopsis
========
Multiple integer overflows in Python have an unspecified impact.
Background
==========
Python is an interpreted, interactive, object-oriented programming
language.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/python < 2.5.4-r2 >= 2.5.4-r2
*>= 2.4.6
Description
===========
Chris Evans reported multiple integer overflows in the expandtabs
method, as implemented by (1) the string_expandtabs function in
Objects/stringobject.c and (2) the unicode_expandtabs function in
Objects/unicodeobject.c.
Impact
======
A remote attacker could exploit these vulnerabilities in Python
applications or daemons that pass user-controlled input to vulnerable
functions. The security impact is currently unknown but may include the
execution of arbitrary code or a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Python 2.5 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.5.4-r2"
All Python 2.4 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.6"
References
