[原文]The local and remote desktop login screens in Microsoft Windows XP before SP2 and 2003 allow remote attackers to cause a denial of service (CPU and memory consumption) by repeatedly using the WinKey+"U" key combination, which causes multiple copies of Windows Utility Manager to be loaded more quickly than they can be closed when the copies detect that another instance is running.


[CNNVD]Microsoft Windows XP服务拒绝漏洞(CNNVD-200412-241)

        Microsoft Windows XP SP2之前版本和2003版本中的本地和远程桌面登录界面存在漏洞。远程攻击者可以通过重复使用WinKey+"U"组合键导致服务拒绝(CPU和内存耗尽),该漏洞导致多个Windows Utility Manager副本载入速度比副本发现另一个实例正在运行时被关闭的速度快。

- 漏洞描述

Microsoft Windows contains a flaw that may allow an attacker to cause the system to hard lock. The issue is triggered when the WinKey and the "U" are held down at the login screen. The system does not properly handle the input causing the system to slow down and eventually use CPU and/or memory before locking up. If the "remote desktop" feature is enabled, this can be used to affect a system remotely.
