Synopsis

The remote Fedora host is missing one or more security updates.

Description

## 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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected php-ZendFramework2 and / or php-zendframework-zendxml packages.
