Solution

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

Summary

Python is an interpreted, interactive, object-oriented programming language often compared to Tcl, Perl, Scheme, or Java. Python includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac and MFC).
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 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)
These updated python packages also include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. For information on the most significant of these changes, usersare directed to the following article on the Red Hat Customer Portal:

All python users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement.
