[原文]A multi-threaded race condition in the Windows RPC DCOM functionality with the MS03-039 patch installed allows remote attackers to cause a denial of service (crash or reboot) by causing two threads to process the same RPC request, which causes one thread to use memory after it has been freed, a different vulnerability than CVE-2003-0352 (Blaster/Nachi), CVE-2003-0715, and CVE-2003-0528, and as demonstrated by certain exploits against those vulnerabilities.


[CNNVD]Microsoft DCOM RPC远程竞争条件漏洞(MS04-012)(CNNVD-200311-072)

        
        Remote Procedure Call (RPC)是Windows 操作系统使用的一种远程过程调用协议,RPC提供进程间交互通信机制,允许在某台计算机上运行程序的无缝地在远程系统上执行代码。协议本身源自开放软件基金会的RPC协议,Microsoft在其基础上增加了自己的一些扩展。
        RPCSS模块中的激活类函数在处理部分激活消息请求时存在问题,远程攻击者可以利用这个漏洞以SYSTEM进程权限在系统上执行任意指令。
        RPCSS模块包含的激活类函数设计用于处理进入的DCOM激活请求,因此实例可提交给请求代理端。通过初始化两个同步的激活请求,然后快速关闭连接,Window RPC实时库处理这特殊的消息时可触发竞争条件问题,这样svchost rpc服务进程堆中会引起小部分破坏,而导致崩溃,进行构建提交请求可能以进程权限在系统上执行任意指令。

- 漏洞讨论

It has been reported that a variant attack in the RPCSS service of Microsoft Windows exists. Because of this, it may be possible for an attacker to mount denial of service attacks and execute arbitrary code on the affected system. The source of the issue is reportedly a multi-thread race condition that occurs when handling a large number of RPC request.

It has been confirmed by the vendor that this issue may be leveraged to execute arbitrary code on the affected system. This may allow an attacker to gain control of the affected system.

- 漏洞利用

Several sources have corroborated that the MS-DCOM-Uni.c exploit does affect patched Windows XP systems (as of MS03-039), and will trigger a denial of service condition. Also, information obtained from a reliable source has confirmed that the exploit will effectively trigger a denial of service on fully patched Windows 2000 systems.

*** An updated version of the universal exploit has been released (rpc3.zip) and it has been reported that it will effectively trigger a denial of service in patched 2k/XP/2003 systems (as recent as MS03-039). This exploit code has been verified by Symantec to successfully crash a patched Windows 2000 system over TCP/UDP port 135.

eEye Digital Security have developed working exploit code that is not publicly available or known to be circulating in the wild.

- 解决方案

Avaya has released an advisory to announce that Avaya System Products shipping on Microsoft platforms are also affected by this vulnerability. Avaya advise that customers follow the Microsoft recommendations for the resolution of this issue. The aforementioned advisory can be viewed at the following location:
http://support.avaya.com/japple/css/japple?temp.groupID=&temp.selectedFamily=128451&temp.selectedProduct=154235&temp.selectedBucket=126655&temp.feedbackState=askForFeedback&temp.documentID=161384&PAGE=avaya.css.CSSLvl1Detail&executeTransaction=avaya.css.UsageUpdate()

Due to the possibility of the existence of working exploit being distributed in the wild, users are advised to apply all available workarounds until the vendor can acknowledge and patch the issue.

Microsoft has released a security bulletin MS04-012 with fixes to address this and other issues.
