VERIFY ADVISORY: http://secunia.com/advisories/17161/ CRITICAL: Moderately critical IMPACT: Privilege escalation, DoS, System access WHERE: >From local network OPERATING SYSTEM: Microsoft Windows XP Professional http://secunia.com/product/22/ Microsoft Windows XP Home Edition http://secunia.com/product/16/ Microsoft Windows Server 2003 Web Edition http://secunia.com/product/1176/ Microsoft Windows Server 2003 Standard Edition http://secunia.com/product/1173/ Microsoft Windows Server 2003 Enterprise Edition http://secunia.com/product/1174/ Microsoft Windows Server 2003 Datacenter Edition http://secunia.com/product/1175/ Microsoft Windows 2000 Server http://secunia.com/product/20/ Microsoft Windows 2000 Professional http://secunia.com/product/1/ Microsoft Windows 2000 Datacenter Server http://secunia.com/product/1177/ Microsoft Windows 2000 Advanced Server http://secunia.com/product/21/ DESCRIPTION: Some vulnerabilities have been reported in Microsoft Windows, which can be exploited by malicious, local users to gain escalated privileges, or by malicious people to cause a DoS (Denial of Service), or compromise a vulnerable system. 1) An unchecked buffer in the MSDTC (Microsoft Distributed Transaction Coordinator) can be exploited to execute arbitrary code or to gain escalated privileges. The vulnerability has been reported in the following versions: * Windows 2000 * Windows XP Service Pack 1 * Windows Server 2003 2) An error in COM+ can be exploited to execute arbitrary code on a vulnerable system via a specially crafted network message, or to gain escalated privileges by running a specially crafted application. The vulnerability has been reported in the following versions: * Windows 2000 (remote code execution) * Windows XP Service Pack 1 (remote code execution) * Windows XP Service Pack 2 (local privilege escalation) * Windows Server 2003 (local privilege escalation) * Windows Server 2003 Service Pack 1 (local privilege escalation) 3) An error in the MSDTC when validating TIP (Transaction Internet Protocol) requests can be exploited to cause the service to stop responding via a specially crafted network message. The malicious TIP message can be transferred through the affected system to another, which causes the MSDTC on both systems to stop responding. Successful exploitation requires that the TIP protocol is enabled for MSDTC. SOLUTION: Apply patches.
