  • 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 version, 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 updates Zend_Crypt_Math to provide cryptographically secure RNG, and updates Zend_Captcha_Word to use these new facilities.
