CVE reference:	CVE-2006-2379

Description: A vulnerability has been reported in Microsoft Windows, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system. The vulnerability is caused due to a boundary error in the TCP/IP protocol driver (tcpip.sys) within the IP source routing mechanism. This can be exploited to cause a buffer overflow via specially crafted ICMP packets with the "Loose-Source" and "Record-Route" IP options set. According to the vendor, successful exploitation most likely causes a crash, but may potentially allow execution of arbitrary code. However, exploitation requires that "IP Source Routing" is enabled (disabled by default on Windows XP SP2 and Windows Server 2003 SP1) or the "Routing and Remote Access Service" is enabled (disabled by default). Solution: Apply patches.
