The Universal Plug and Play (UPnP) service allows computers to
discover and use network-based devices. Windows ME and XP include
native UPnP services; Windows 98 and 98SE do not include a native
UPnP service, but one can be installed via the Internet Connection
Sharing client that ships with Windows XP.

A vulnerability results because the UPnP service does not correctly
handle certain types of invalid UPnP requests. On Windows 98, 98SE,
and ME systems, receiving such a request could cause a variety of
effects ranging from slow performance to system failure. On
Windows XP, the effect is less serious as the flaw consists of a
memory leak. Each time a Windows XP system received such a request,
a small amount of system memory would become unavailable;
if repeated many times, it could deplete system resources to
the point where performance slowed or stopped altogether

Affected Software:

Microsoft Windows 98
Microsoft Windows 98SE
Microsoft Windows ME
Microsoft Windows XP
Note: Windows 98 and 98SE are only affected if the Internet Connection Sharing that ships with Windows XP has been installed on the machine.
