GLSA-200807-16 : Python: Multiple vulnerabilities

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200807-16
(Python: Multiple vulnerabilities)

Multiple vulnerabilities were discovered in Python:
David Remahl of Apple Product Security reported several integer
overflows in core modules such as stringobject, unicodeobject,
bufferobject, longobject, tupleobject, stropmodule, gcmodule,
mmapmodule (CVE-2008-2315).
David Remahl of Apple Product Security also reported an integer
overflow in the hashlib module, leading to unreliable cryptographic
digest results (CVE-2008-2316).
Justin Ferguson reported multiple buffer overflows in unicode string
processing that only affect 32bit systems (CVE-2008-3142).
The Google Security Team reported multiple integer overflows
(CVE-2008-3143).
Justin Ferguson reported multiple integer underflows and overflows in
the PyOS_vsnprintf() function, and an off-by-one error when passing
zero-length strings, leading to memory corruption (CVE-2008-3144).

Impact :

A remote attacker could exploit these vulnerabilities in Python
applications or daemons that pass user-controlled input to vulnerable
functions. Exploitation might lead to the execution of arbitrary code
or a Denial of Service. Vulnerabilities within the hashlib might lead
to weakened cryptographic protection of data integrity or authenticity.

Workaround :

There is no known workaround at this time.

Solution :

All Python 2.4 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-lang/python-2.4.4-r14'
All Python 2.5 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-lang/python-2.5.2-r6'
Please note that Python 2.3 is masked since June 24, and we will not be
releasing updates to it. It will be removed from the tree in the near
future.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
