-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:097 http://www.mandriva.com/security/ _______________________________________________________________________ Package : python Date : June 20, 2012 Affected: 2011. _______________________________________________________________________ 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 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-2011-4944 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 2011: 3a636759b5bad1fbc2d1e65d09f065e8 2011/i586/libpython2.7-2.7.2-2.2-mdv2011.0.i586.rpm 9a1cca4bb94f9d48c9da77b890489137 2011/i586/libpython-devel-2.7.2-2.2-mdv2011.0.i586.rpm c6bf8a9f3f3fb4dde435d369bfde2491 2011/i586/python-2.7.2-2.2-mdv2011.0.i586.rpm 3f920fd4ea52ce46d3916f03ffc6f823 2011/i586/python-docs-2.7.2-2.2-mdv2011.0.i586.rpm 0ffc3a9eef594322deffa1b2dd740e85 2011/i586/tkinter-2.7.2-2.2-mdv2011.0.i586.rpm 43d6123beffdcb8d96feabc291497071 2011/i586/tkinter-apps-2.7.2-2.2-mdv2011.0.i586.rpm 50475c472b29fe6be76697b642ed7339 2011/SRPMS/python-2.7.2-2.2.src.rpm Mandriva Linux 2011/X86_64: d6734d8d3f14fa0b5992621dc41163b2 2011/x86_64/lib64python2.7-2.7.2-2.2-mdv2011.0.x86_64.rpm 9f352fe74256c707c817257c0221307d 2011/x86_64/lib64python-devel-2.7.2-2.2-mdv2011.0.x86_64.rpm 8d64c9235837b188c3e706e7d2ea7800 2011/x86_64/python-2.7.2-2.2-mdv2011.0.x86_64.rpm 4b834815a0d8bac098870cc0755c63d5 2011/x86_64/python-docs-2.7.2-2.2-mdv2011.0.x86_64.rpm 8f0d7f2fba81c33dece3d94e0c03b7d9 2011/x86_64/tkinter-2.7.2-2.2-mdv2011.0.x86_64.rpm 0883aad29e1942356169eb3b9017e6d5 2011/x86_64/tkinter-apps-2.7.2-2.2-mdv2011.0.x86_64.rpm 50475c472b29fe6be76697b642ed7339 2011/SRPMS/python-2.7.2-2.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
