    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.
