Jose-php Information Disclosure Vulnerability

jose-php is suitable for PHP JSON object signature and encryption library . A security vulnerability exists in versions of jose-php before 2.2.1, due to the lack of a random padding mechanism in the implementation of the RSA 1.5 algorithm in the JWE.php/JOSEJWE class. A remote attacker can obtain...

Code injection

The GatewayScript modules on IBM DataPower Gateways with software 7.2.0.x before 7.2.0.1, when the GatewayScript decryption API or a JWE decrypt action is enabled, do not require signed ciphertext data, which makes it easier for remote attackers to obtain plaintext data via a padding-oracle attac...
