    Summary: SimpleSAMLphp Incorrect IV generation for encryption

    Details: The aesEncrypt method in `lib/SimpleSAML/Utils/Crypto.php` in SimpleSAMLphp 1.14.x through 1.14.11 makes it easier for context-dependent attackers to bypass the encryption protection mechanism by leveraging use of the first 16 bytes of the secret key as the initialization vector (IV).
