Vulnerability in RPC on Windows DNS Server Could Allow Remote Code Execution.

Published: April 12, 2007 | Updated: April 15, 2007

Microsoft
is investigating new public reports of a limited attack exploiting a
vulnerability in the Domain Name System (DNS) Server Service in
Microsoft Windows 2000 Server Service Pack 4, Windows Server 2003
Service Pack 1, and Windows Server 2003 Service Pack 2. Microsoft
Windows 2000 Professional Service Pack 4, Windows XP Service Pack 2,
and Windows Vista are not affected as these versions do not contain the
vulnerable code.

Microsoft’s initial investigation reveals that
the attempts to exploit this vulnerability could allow an attacker to
run code in the security context of the Domain Name System Server
Service, which by default runs as Local SYSTEM.

Upon completion
of this investigation, Microsoft will take appropriate action to help
protect our customers. This may include providing a security update
through our monthly release process or providing an out-of-cycle
security update, depending on customer needs.
