[原文]The Windows Media server allows remote attackers to cause a denial of service via a series of client handshake packets that are sent in an improper sequence, aka the "Misordered Windows Media Services Handshake" vulnerability.


[CNNVD]Microsoft Windows Media Services Handshake序列DoS序列漏洞(CNNVD-200002-063)

        Windows Media服务器存在漏洞。远程攻击者借助一系列在不正确序列中传送的客户端handshake包导致拒绝服务,又称为"Misordered Windows Media Services Handshake"漏洞。

Misordered handshake sequences sent to a Windows Media Unicast Server via Windows Media Player will cause the server to crash. Restarting the Unicast Service, including any open sessions during the time of the crash, is required in order to regain normal functionality. This is due to the dependency of the application on successfully completing asychronous handshake requests in a proper sequential order between the client and the server.
