These random number generators are used in the following method calls:\n```\nZend_Ldap_Attribute::createPassword\nZend_Form_Element_Hash::_generateHash\nZend_Gdata_HttpClient::filterHttpRequest\nZend_Filter_Encrypt_Mcrypt::_srand\nZend_OpenId::randomBytes\n```\nIn 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.\n\nMoreover, 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.","public_affected_ranges":["ECOSYSTEM: introduced 1.12.0; fixed 1.12.18"]}],"null_published_at":"2026-10-31T22:13:22.830Z","source_updated_at":"2024-12-04T05:41:20.457Z","source_disclosed_at":"2024-06-07T22:26:25.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:42:10.677Z"}],"next_cursor":null,"snapshot_revision":"42594"}
