Red Hat Security Advisory 2017-1868-01 - Python is an interpreted, interactive, object-oriented programming language, which 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. Security Fix: The Python standard library HTTP client modules did not perform verification of TLS/SSL certificates when connecting to HTTPS servers. A man-in-the-middle attacker could use this flaw to hijack connections and eavesdrop or modify transferred data.

The python27 packages provide a stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and PostgreSQL. The python27 Software Collection has been upgraded to version 2.7.13, which provides a number of bug fixes and enhancements over the previous version.
b074a1dc77a800a7bb251bd62b55be188b14ba2806e7964428a041350866d803Mandriva Linux Security Advisory 2015-075 - A vulnerability was reported in Python's socket module, due to a boundary error within the sock_recvfrom_into() function, which could be exploited to cause a buffer overflow. This could be used to crash a Python application that uses the socket.recvfrom_info() function or, possibly, execute arbitrary code with the permissions of the user running vulnerable Python code. This updates the python package to version 2.7.6, which fixes several other bugs, including denial of service flaws due to unbound readline() calls in the ftplib and nntplib modules. Denial of service flaws due to unbound readline() calls in the imaplib, poplib, and smtplib modules. A gzip bomb and unbound read denial of service flaw in python XMLRPC library. Python are susceptible to arbitrary process memory reading by a user or adversary due to a bug in the _json module caused by insufficient bounds checking. The bug is caused by allowing the user to supply a negative value that is used an an array index, causing the scanstring function to access process memory outside of the string it is intended to access. The CGIHTTPServer Python module does not properly handle URL-encoded path separators in URLs. This may enable attackers to disclose a CGI script's source code or execute arbitrary scripts in the server's document root. Python before 2.7.8 is vulnerable to an integer overflow in the buffer type. When Python's standard library HTTP clients (httplib, urllib, urllib2, xmlrpclib) are used to access resources with HTTPS, by default the certificate is not checked against any trust store, nor is the hostname in the certificate checked against the requested host. It was possible to configure a trust root to be checked against, however there were no faculties for hostname checking. The python-pip and tix packages was added due to missing build dependencies.
