Synopsis
========

A heap-based buffer overflow in PyCrypto might allow remote attackers
to execute arbitrary code.

Background
==========

The Python Cryptography Toolkit (PyCrypto) is a collection of both
secure hash functions (such as SHA256 and RIPEMD160), and various
encryption algorithms (AES, DES, RSA, ElGamal, etc.).

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 dev-python/pycrypto < 2.6.1-r2 >= 2.6.1-r2

Description
===========

A heap-based buffer overflow vulnerability has been discovered in
PyCrypto. Please review the CVE identifier referenced below for
details.

Impact
======

A remote attacker, able to control the mode of operation in PyCrypto’s
AES module, could possibly execute arbitrary code with the privileges
of the process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PyCrypto users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-python/pycrypto-2.6.1-r2”
