I have not seen anything yet from Microsoft about the TCP RST possible
attacks that are detailed in the following bulletins:

Technical Cyber Security Alert TA04-111A
Vulnerabilities in TCP
http://www.us-cert.gov/cas/techalerts/TA04-111A.html

SANS
http://isc.incidents.org/diary.php?date=2004-04-20&isc=9a4c61bc294b1039c8ecacff03534c2c
CVE entry: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0230
Cisco announcement:
http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-ios.shtml

If I understand correctly, an attack would affect any long term session TCP
communications. Since Windows Server 2003 and 2000 running as Domain
Controllers are not supported using IPSEC (one mentioned work around), what
possible attacks will we be facing in the future? Does standard Windows
networking (SMB) depend on this kind of communication? Can a Windows box
setup to do routing (I don't remember if RRAS supports BGP) be affected by
these kinds of attacks?
