Detail

Multiple vulnerabilities have been identified and fixed in python:

The is_cgi method in CGIHTTPServer.py in the CGIHTTPServer module in Python 2.5, 2.6, and 3.0 allows remote attackers to read script source code via an HTTP GET request that lacks a / (slash) character at the beginning of the URI (CVE-2011-1015).

A flaw was found in the Python urllib and urllib2 libraries where they would not differentiate between different target URLs when handling automatic redirects. This caused Python applications using these modules to follow any new URL that they understood, including the file:// URL type. This could allow a remote server to force a local Python application to read a local file instead of the remote one, possibly exposing local files that were not meant to be exposed (CVE-2011-1521).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more: http://store.mandriva.com/product_info.php?cPath=149&products_id=490

The updated packages have been patched to correct this issue.

Id Description
71361 Python CGIHTTPServer Module cgi-bin Code Disclosure

Python contains a flaw that may lead to an unauthorized information disclosure.  The issue is triggered when the 'CGIHTTPServer' module does not handle HTTP requests to scripts in the 'cgi-bin' directory correctly, which will disclose CGI script source code to a remote attacker via crafted requests to the server.
71330 Python urllib.request file:// URL Handler Redirect Issue

Python contains a flaw related to the urllib/urlib2 redirect handling allowing file:// URL schemes. This may allow a remote attacker to use a crafted HTTP redirect response to disclose sensitive information or cause a denial of service via resource consumption.
