RHSA-2011:0554 - Moderate: python security, bug fix, and enhancement update

Synopsis

Moderate: python security, bug fix, and enhancement update

Type/Severity

Security Advisory Moderate

Topic

Updated python packages that fix three security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

Python is an interpreted, interactive, object-oriented programming language.

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)

A race condition was found in the way the Python smtpd module handled new connections. A remote user could use this flaw to cause a Python script using the smtpd module to terminate. (CVE-2010-3493)

An information disclosure flaw was found in the way the Python CGIHTTPServer module processed certain HTTP GET requests. A remote attacker could use a specially-crafted request to obtain the CGI script's source code. (CVE-2011-1015)

This erratum also upgrades Python to upstream version 2.6.6, and includes a number of bug fixes and enhancements. Documentation for these bug fixes and enhancements is available from the Technical Notes document, linked to in the References section.

All users of Python are advised to upgrade to these updated packages, which correct these issues, and fix the bugs and add the enhancements noted in the Technical Notes.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
