Vulnerability Name:

CVE-2005-2359 (CCN-21551)

Assigned:2005-07-27
Published:2005-07-27
Updated:2017-07-11
Summary: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.
