3. Description:

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(es):

* A vulnerability was discovered in Python, in the built-in zipimporter. A
specially crafted zip file placed in a module path such that it would be
loaded by a later "import" statement could cause a heap overflow, leading
to arbitrary code execution. (CVE-2016-5636)

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section.
