Message-Id: <E1ShNUj-00051f-1s@titan.mandriva.com> Date: Wed, 20 Jun 2012 18:11:00 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2012:096 ] python -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:096 http://www.mandriva.com/security/ _______________________________________________________________________ Package : python Date : June 20, 2012 Affected: 2010.1 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been discovered and corrected in python: The _ssl module would always disable the CBC IV attack countermeasure (CVE-2011-3389). A flaw was found in the way the Python SimpleHTTPServer module generated directory listings. An attacker able to upload a file with a specially-crafted name to a server could possibly perform a cross-site scripting (XSS) attack against victims visiting a listing page generated by SimpleHTTPServer, for a directory containing the crafted file (if the victims were using certain web browsers) (CVE-2011-4940). A race condition was found in the way the Python distutils module set file permissions during the creation of the .pypirc file. If a local user had access to the home directory of another user who is running distutils, they could use this flaw to gain access to that user's .pypirc file, which can contain usernames and passwords for code repositories (CVE-2011-4944). A flaw was found in the way the Python SimpleXMLRPCServer module handled clients disconnecting prematurely. A remote attacker could use this flaw to cause excessive CPU consumption on a server using SimpleXMLRPCServer (CVE-2012-0845). Hash table collisions CPU usage DoS for the embedded copy of expat (CVE-2012-0876). A denial of service flaw was found in the implementation of associative arrays (dictionaries) in Python. An attacker able to supply a large number of inputs to a Python application (such as HTTP POST request parameters sent to a web application) that are used as keys when inserting data into an array could trigger multiple hash function collisions, making array operations take an excessive amount of CPU time. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions (CVE-2012-1150). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3389 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4940 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4944 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0845 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0876 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-1150 _______________________________________________________________________ Updated Packages: Mandriva Linux 2010.1: c3efceda4babb96954960fd81d86f6c4 2010.1/i586/libpython2.6-2.6.5-2.5mdv2010.2.i586.rpm b000fe745cd27bf32751c850a1c19885 2010.1/i586/libpython2.6-devel-2.6.5-2.5mdv2010.2.i586.rpm 3bfcc2467a842934f40c6c6b57e29348 2010.1/i586/python-2.6.5-2.5mdv2010.2.i586.rpm 35e1c1493a783256af91b05ce91e7a02 2010.1/i586/python-docs-2.6.5-2.5mdv2010.2.i586.rpm 74ea05d4abdfe330810dba89ab2ec559 2010.1/i586/tkinter-2.6.5-2.5mdv2010.2.i586.rpm c829d89145ff97ee0349a587d55b8032 2010.1/i586/tkinter-apps-2.6.5-2.5mdv2010.2.i586.rpm 8674202b9c359c7ccf1fc224a2e4a2db 2010.1/SRPMS/python-2.6.5-2.5mdv2010.2.src.rpm Mandriva Linux 2010.1/X86_64: f732345e85d029cd7742e0e146a56b1a 2010.1/x86_64/lib64python2.6-2.6.5-2.5mdv2010.2.x86_64.rpm 2d0592f1f0f1cdd3a3e1056d414720b2 2010.1/x86_64/lib64python2.6-devel-2.6.5-2.5mdv2010.2.x86_64.rpm 4b503d77364687b8bd1d6da4d48b8d48 2010.1/x86_64/python-2.6.5-2.5mdv2010.2.x86_64.rpm 489c6861df52431f01dfd13ba0389b58 2010.1/x86_64/python-docs-2.6.5-2.5mdv2010.2.x86_64.rpm 487ee074b815870c0e02f998943539a6 2010.1/x86_64/tkinter-2.6.5-2.5mdv2010.2.x86_64.rpm 032ea3bf5e7a941df3630ff23de9506d 2010.1/x86_64/tkinter-apps-2.6.5-2.5mdv2010.2.x86_64.rpm 8674202b9c359c7ccf1fc224a2e4a2db 2010.1/SRPMS/python-2.6.5-2.5mdv2010.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
