GHSA-8xhv-gqm4-3w99 ZendFramework1 Potential Insufficient Entropy Vulnerability

• Packagist zendframework/zendframework1: >= 1.12.0, < 1.12.18 → fixed in 1.12.18

We discovered several methods used to generate random numbers in ZF1 that potentially used insufficient entropy. These random number generators are used in the following method calls: ``` Zend_Ldap_Attribute::createPassword Zend_Form_Element_Hash::_generateHash Zend_Gdata_HttpClient::filterHttpRequest Zend_Filter_Encrypt_Mcrypt::_srand Zend_OpenId::randomBytes ``` In each case, the methods were using rand() or mt_rand(), neither of which can generate cryptographically secure values. This could potentially lead to information disclosure should an attacker be able to brute force the random number generation. Moreover, we discovered a potential security issue in the usage of the openssl_random_pseudo_bytes() function in Zend_Crypt_Math::randBytes, reported in PHP BUG #70014, and the security implications reported in a discussion on the random_compat library.
