GLSA-200807-01 : Python: Multiple integer overflows

This script is Copyright (C) 2008-2016 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200807-01
(Python: Multiple integer overflows)

Multiple vulnerabilities were discovered in Python:
Remahl reported multiple integer overflows in the file imageop.c,
leading to a heap-based buffer overflow (CVE-2008-1679). This issue is
due to an incomplete fix for CVE-2007-4965.
Justin Ferguson
discovered that an integer signedness error in the zlib extension
module might trigger insufficient memory allocation and a buffer
overflow via a negative signed integer (CVE-2008-1721).
Ferguson discovered that insufficient input validation in the
PyString_FromStringAndSize() function might lead to a buffer overflow

Impact :

A remote attacker could exploit these vulnerabilities to cause a Denial
of Service or possibly the remote execution of arbitrary code with the
privileges of the user running Python.

Workaround :

There is no known workaround at this time.

Solution :

The imageop module is no longer built in the unaffected versions.
All Python 2.3 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-lang/python-2.3.6-r6'
All Python 2.4 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-lang/python-2.4.4-r13'

Risk factor :

High / CVSS Base Score : 9.3
CVSS Temporal Score : 7.3
Public Exploit Available : true
