TITLE

Microsoft Forefront TMG MBE and ISA Server Service disruption in firewall engines (DoS) Vulnerabilities

DESCRIPTION

The firewall engine in Microsoft Forefront Threat Management Gateway, Medium Business Edition (TMG MBE); and Internet Security and Acceleration (ISA) Server 2004 SP3, 2006, 2006 Supportability Update, and 2006 SP1; does not properly manage the session state of web listeners, which allows remote attackers to cause a denial of service (many stale sessions) via crafted packets, aka "Web Proxy TCP State Limited Denial of Service Vulnerability.". Microsoft ISA Server and Forefront Threat Management Gateway are prone to a remote denial-of-service vulnerability. A remote, anonymous attacker could exploit this issue to cause the Web proxy listener to become unresponsive, denying service legitimate users. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 National Cyber Alert System Technical Cyber Security Alert TA09-104A Microsoft Updates for Multiple Vulnerabilities Original release date: April 14, 2009 Last revised: -- Source: US-CERT Systems Affected * Microsoft Windows * Microsoft Office * Microsoft Windows Server * Microsoft ISA Server Overview Microsoft has released updates that address vulnerabilities in Microsoft Windows, Office, Windows Server, and ISA Server.
