Synopsis
========
Multiple integer overflow vulnerabilities have been discovered in
Python, possibly resulting in the execution of arbitrary code or a
Denial of Service.
Background
==========
Python is an interpreted, interactive, object-oriented programming
language.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/python < 2.4.4-r6 *>= 2.3.6-r3
>= 2.4.4-r6
Description
===========
Slythers Bro discovered multiple integer overflows in the imageop
module, one of them in the tovideo() method, in various locations in
files imageop.c, rbgimgmodule.c, and also in other files.
Impact
======
A remote attacker could entice a user to process specially crafted
images with an application using the Python imageop module, resulting
in the execution of arbitrary code with the privileges of the user
running the application, or a Denial of Service. Note that this
vulnerability may or may not be exploitable, depending on the
application using the module.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Python 2.3.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.3.6-r3"
All Python 2.4.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.4-r6"
