    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.
