Description:
A vulnerability was reported in the Windows DNS service RPC interface. A remote user can execute arbitrary code on the target system.
A remote user can send a specially crafted RPC packet to the RPC interface of the DNS server to trigger a stack overflow and execute arbitrary code on the target system. The code will run with the privileges of the target DNS service, which runs with Local System privileges by default.
A remote authenticated user can also exploit this vulnerability via TCP/UDP ports 139 and 445.
The name resolution function running on port 53 is not affected.
The vulnerable code resides on Windows server systems, not client systems.
Windows 2000 Professional SP4, Windows XP SP2, and Windows Vista are not affected.
This vulnerability was originally reported as being actively exploited in limited situations. On April 17, 2006 (UTC), Microsoft reported seeing a new attack that "does not appear widespread."
