### SECURITY UPDATES

  - **ZF2015-09**: `Zend\Captcha\Word` generates a 'word'
    for a CAPTCHA challenge by selecting a sequence of
    random letters from a character set. Prior to this
    vulnerability announcement, the selection was performed
    using PHP's internal `array_rand()` function. This
    function does not generate sufficient entropy due to its
    usage of `rand()` instead of more cryptographically
    secure methods such as `openssl_pseudo_random_bytes()`.
    This could potentially lead to information disclosure
    should an attacker be able to brute force the random
    number generation. This release contains a patch that
    replaces the `array_rand()` calls to use
    `Zend\Math\Rand::getInteger()`, which provides better
    RNG.

  - **ZF2015-10**: `Zend\Crypt\PublicKey\Rsa\PublicKey` has
    a call to `openssl_public_encrypt()` which used PHP's
    default `$padding` argument, which specifies
    `OPENSSL_PKCS1_PADDING`, indicating usage of PKCS1v1.5
    padding. This padding has a known vulnerability, the
    [Bleichenbacher's chosen-ciphertext
    attack](http://crypto.stackexchange.com/questions/12688/
    can-you-explain-bleichenbachers-cca-attack-on-pkcs1-v1-5
    ), which can be used to recover an RSA private key. This
    release contains a patch that changes the padding
    argument to use `OPENSSL_PKCS1_OAEP_PADDING`.

    Users upgrading to this version may have issues
    decrypting previously stored values, due to the change
    in padding. If this occurs, you can pass the constant
    `OPENSSL_PKCS1_PADDING` to a new `$padding` argument in
    `Zend\Crypt\PublicKey\Rsa::encrypt()` and `decrypt()`
    (though typically this should only apply to the 
latter) :

    ```php $decrypted = $rsa->decrypt($data, $key, $mode,
    OPENSSL_PKCS1_PADDING); ```

    where `$rsa` is an instance of
    `Zend\Crypt\PublicKey\Rsa`.

    (The `$key` and `$mode` argument defaults are `null` and
    `Zend\Crypt\PublicKey\Rsa::MODE_AUTO`, if you were not
    using them previously.)

    We recommend re-encrypting any such values using the new
    defaults.
