Synopsis
========

A flaw in PyCrypto allow remote attackers to obtain sensitive
information.

Background
==========

PyCrypto is the Python Cryptography Toolkit.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-python/pycrypto        <= 2.6.1-r2                Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

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

It was discovered that PyCrypto incorrectly generated ElGamal key
parameters.

Impact
======

Attackers may be able to obtain sensitive information by reading
ciphertext data.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

Gentoo has discontinued support for PyCrypto. We recommend that users
unmerge PyCrypto:

 # emerge --unmerge "dev-python/pycrypto"
 
NOTE: The Gentoo developer(s) maintaining PyCrypto have discontinued
support at this time. PyCryptodome is the canonical successor to
PyCrypto.
