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) A memory allocation error in the MSDTC (Microsoft Distributed Transaction Coordinator) interface proxy can be exploited to execute arbitrary code or to gain escalated privileges. The vulnerability is caused due to an error in the "MIDL_user_allocate()" function which allocates a single 4KB page of memory regardless of the actual amount of memory requested.
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 lead to a DoS. This can be exploited by sending a sequence of commands to cause the MSDTC service to connect-back to a malicious server. The malicious server can then send an unexpected protocol command during the reconnection request to crash the MSDTC server.
Successful exploitation requires that the TIP protocol is enabled for MSDTC.
4) An error in the MSDTC when validating TIP (Transaction Internet Protocol) requests can be exploited to cause the MSDTC service to flood a specific IP address and port via a specific sequence of commands.
Successful exploitation requires that the TIP protocol is enabled for MSDTC.
