> DESCRIPTION:
> h07 has discovered a vulnerability in Microsoft Windows, which can be
> exploited by malicious people to cause a DoS (Denial of Service).
> 
> The vulnerability is caused due to an error in the handling of
> "RpcGetPrinterData()" RPC requests within the Print Spooler service
> (spoolsv.exe). This can be exploited to consume almost all available
> memory via a specially crafted packet, which may result in a system
> crash.
> 
> The vulnerability is confirmed on a fully patched Windows 2000 SP4
> system. Other versions may also be affected.
> 
> SOLUTION:
> Restrict access to the service or disable the Print Spooler service.
