Update Information:
## 2.4.10 (2016-05-09) - Fix HeaderValue throwing an exception on legal
characters ## 2.4.9 (2015-11-23) ### 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.
