Message-Id: <E1Sli5d-0000Yt-Af@titan.mandriva.com> Date: Mon, 02 Jul 2012 16:59:00 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2012:096-1 ] python -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:096-1 http://www.mandriva.com/security/ _______________________________________________________________________ Package : python Date : July 2, 2012 Affected: Enterprise Server 5.0 _______________________________________________________________________ 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. Update: Packages for Mandriva Enterprise Server 5 is also being provided. _______________________________________________________________________ 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 Enterprise Server 5: e18f146e6c8aa316adb5d19a0de2cdef mes5/i586/libpython2.5-2.5.2-5.12mdvmes5.2.i586.rpm f425a7831028c28f98bac0d95ee532ce mes5/i586/libpython2.5-devel-2.5.2-5.12mdvmes5.2.i586.rpm 153ff4e78256ec9b0b89f5ecd7ed317c mes5/i586/python-2.5.2-5.12mdvmes5.2.i586.rpm bbff1780014007b0c95491c74d3dc82b mes5/i586/python-base-2.5.2-5.12mdvmes5.2.i586.rpm e73ffb5aeff47d2008b0bdb99623579f mes5/i586/python-docs-2.5.2-5.12mdvmes5.2.i586.rpm af4d7f8f20f7cf7b2beb77dbd06f6992 mes5/i586/tkinter-2.5.2-5.12mdvmes5.2.i586.rpm 268850f5dd79335c129fa84469d39e20 mes5/i586/tkinter-apps-2.5.2-5.12mdvmes5.2.i586.rpm 0248488ef4499a61ba9ef31061325f1e mes5/SRPMS/python-2.5.2-5.12mdvmes5.2.src.rpm Mandriva Enterprise Server 5/X86_64: 6ee32ebb3873a3e01def5984dfa951c7 mes5/x86_64/lib64python2.5-2.5.2-5.12mdvmes5.2.x86_64.rpm 9e7d5a39d2b224bd9141e6851350e43d mes5/x86_64/lib64python2.5-devel-2.5.2-5.12mdvmes5.2.x86_64.rpm f798622e3b9f9795c373be0d90008684 mes5/x86_64/python-2.5.2-5.12mdvmes5.2.x86_64.rpm 916fb7c6e716daaf5269086b9477efcf mes5/x86_64/python-base-2.5.2-5.12mdvmes5.2.x86_64.rpm 53f14e4e8d6140603acac82004bd12c9 mes5/x86_64/python-docs-2.5.2-5.12mdvmes5.2.x86_64.rpm ff348190df6007b7d0b043ac153f35dd mes5/x86_64/tkinter-2.5.2-5.12mdvmes5.2.x86_64.rpm d7f55af87f3e3ea045b556f91c09333b mes5/x86_64/tkinter-apps-2.5.2-5.12mdvmes5.2.x86_64.rpm 0248488ef4499a61ba9ef31061325f1e mes5/SRPMS/python-2.5.2-5.12mdvmes5.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
