DOS: IGMP Oversize
This signature detects attempts to exploit a known vulnerability against the IGMP header in Microsoft Windows 98 and 2000 TCP/IP stacks. Attackers can send maliciously crafted IGMP headers to cause the stack to fail and cause a denial of service.
Extended Description
The Windows 98 and Windows 2000 TCP/IP stacks were not built to reliably tolerate malformed IGMP headers. When one is received, the stack will sometimes fail with unpredictable results ranging from a Blue Screen to instantaneous reboot.
