Description:
A vulnerability has been identified in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.
The cause of the vulnerability is twofold. The RPC service performs inadequate input validation before passing data to a DCOM (Distributed Component Object Model) interface. This interface has a boundary error in the "CoGetInstanceFromFile" API when handling the "szName" parameter, which can be exploited by sending a RPC packet containing an overly long, specially crafted filename.
Successful exploitation may cause a buffer overflow allowing execution of arbitrary code on the vulnerable system with "LocalSystem" privileges.
It has been reported that this vulnerability may be exploited through the following ports:
135/udp, 135/tcp, 139/tcp, 445/tcp, 593/tcp
Depending on your configuration, other RPC enabled ports could possibly open attack vectors too.
Solution:
Apply patch via WindowsUpdate or manually (NOTE: Reportedly, the patch for Windows 2000 doesn't fix the vulnerability adequately).
