Detail

Problem Description:

Updated python27 collection packages that fix multiple security issues and several bugs are now available as part of Red Hat Software Collections 2.

Red Hat Product Security 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.

2. Relevant releases/architectures:

Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 7) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.5) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64

3. Description:

Python is an interpreted, interactive, object-oriented programming language that supports modules, classes, exceptions, high-level dynamic data types, and dynamic typing. The python27 collection provide a stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and PostgreSQL.

The python27-python packages have been upgraded to upstream version 2.7.8, which provides numerous bug fixes over the previous version. (BZ#1167912)

The following security issues were fixed in the python27-python component:

It was discovered that the socket.recvfrom_into() function failed to check the size of the supplied buffer. This could lead to a buffer overflow when the function was called with an insufficiently sized buffer. (CVE-2014-1912)

It was discovered that the Python xmlrpclib module did not restrict the size of gzip-compressed HTTP responses. A malicious XMLRPC server could cause an XMLRPC client using xmlrpclib to consume an excessive amount of memory. (CVE-2013-1753)

It was discovered that multiple Python standard library modules implementing network protocols (such as httplib or smtplib) failed to restrict the sizes of server responses. A malicious server could cause a client using one of the affected modules to consume an excessive amount of memory. (CVE-2013-1752)

It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose the source code of the scripts in the cgi-bin directory. (CVE-2014-4650)

An integer overflow flaw was found in the way the buffer() function handled its offset and size arguments. An attacker able to control these arguments could use this flaw to disclose portions of the application memory or cause it to crash. (CVE-2014-7185)

The following security issue was fixed in the python27-python and python27-python-simplejson components:

A flaw was found in the way the json module handled negative index arguments passed to certain functions (such as raw_decode()). An attacker able to control the index value passed to one of the affected functions could possibly use this flaw to disclose portions of the application memory. (CVE-2014-4616)

In addition, this update adds the following enhancement:

* The python27 Software Collection now includes the python-wheel and python-pip modules. (BZ#994189, BZ#1167902)

All python27 users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. All running python27 instances must be restarted for this update to take effect.

4. Solution:

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