Mandriva Update for python MDVSA-2012:097 (python)

Published: 2012-06-22 05:02:48
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Summary:
The remote host is missing an update for the 'python' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
python on Mandriva Linux 2011.0

Recommendations:
Please Install the Updated Packages.

Technical Details:
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 Linux Distribution Packages have been patched to correct these issues.

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
