Descriptions

CiphertextHeader.java in Cryptacular 1.2.3, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data.

El archivo CiphertextHeader.java en Cryptacular versión 1.2.3, como es usado en Apereo CAS y otros productos, permite a atacantes activar una asignación de memoria excesiva durante una operación de decodificación, porque la longitud de la matriz nonce asociada con el "new byte" puede depender de una entrada no confiable dentro del encabezado de datos codificados.
