Name        : python-crypto
Product : Fedora 24
Version : 2.6.1
Release : 13.fc24
URL : http://www.pycrypto.org/

Update Information:

A heap-buffer overflow vulnerability was discovered in pycrypto leading to
arbitrary code execution. All users of pycrypto's AES module that allow the
mode
of operation to be specified by an attacker, check for ECB explicitly and
create
the objects without specifying an IV are vulnerable to this issue. This is
CVE-2013-7459.
