A heap-buffer overflow vulnerability was discovered in pycrypto leading to arbitrary code execution

Summary

PyCrypto is a collection of both secure hash functions (such as MD5 and

SHA), and various encryption algorithms (AES, DES, RSA, ElGamal, etc.).

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.
