GLSA-200807-16 : Python: Multiple vulnerabilities

High Nessus Plugin ID 33782

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.
