MSDTC NdrAllocate() invalid memory access denial of service
| msdtc-network-message-dos (25559) |  Low Risk |
Description:
The Microsoft Distributed Transaction Service Coordinator (MSDTC) installed on Microsoft Windows is vulnerable to a denial of service attack, caused by a buffer overflow in the MSDTC NdrAllocate() function. By sending a specially-crafted network message to the system, a remote attacker could cause the MSDTC service to stop responding.
Platforms Affected:
- Microsoft, Windows 2000 SP4
- Microsoft, Windows 2003
- Microsoft, Windows 2003 Server Itanium
- Microsoft, Windows 2003 Server SP1 Itanium
- Microsoft, Windows XP SP1
- Microsoft, Windows XP SP2
Remedy:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS06-018. See References.
Consequences:
Denial of Service
