Descriptions

The AES-XCBC-MAC algorithm in IPsec in FreeBSD 5.3 and 5.4, when used for authentication without other encryption, uses a constant key instead of the one that was assigned by the system administrator, which can allow remote attackers to spoof packets to establish an IPsec session.

El algoritmo AES-XCBC-MACen IPsec en FreeBSD 5.3 y 5.4, cuando se usa para autentificación sin otra encriptación, usa una clave constante (en vez de la que asigne el administrador del sistema). Esto puede permitir que atacantes remotos establezcan una sesión IPsec.

IPsec is a security protocol for the Internet Protocol networking layer. It provides a combination of encryption and authentication of system, using several possible cryptography algorithms. A programming error in the implementation of the AES-XCBC-MAC algorithm for authentication resulted in a constant key being used instead of the key specified by the system administrator.
