A vulnerability, which was classified as critical, was found in FreeBSD up to 4.5 (Operating System). Affected is an unknown functionality of the component SYN Cookie Handler. The manipulation with an unknown input leads to a authentication spoofing vulnerability. CWE is classifying the issue as CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. This is going to have an impact on confidentiality, and integrity. CVE summarizes:

The implementation of SYN cookies (syncookies) in FreeBSD 4.5 through 5.0-RELEASE-p3 uses only 32-bit internal keys when generating syncookies, which makes it easier for remote attackers to conduct brute force ISN guessing attacks and spoof legitimate traffic.

The bug was discovered 02/24/2003. The weakness was disclosed 02/24/2003 by Mike Silbersack (Website). The advisory is available at ftp.freebsd.org. This vulnerability is traded as CVE-2003-1230 since 08/17/2005. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (11397). The entry 21166 is pretty similar.
