The Server service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, and 7 Pre-Beta allows remote attackers to execute arbitrary code via a crafted RPC request that triggers the overflow during path canonicalization, as exploited in the wild by Gimmiv.A in October 2008, aka “Server Service Vulnerability.”
MS08-067 includes the following information about the Microsoft Server service:
The Server service provides RPC support, file print support and named pipe sharing over the network. The Server service allows the sharing of your local resources (such as disks and printers) so that other users on the network can access them. It also allows named pipe communication between applications running on other computers and your computer, which is used for RPC.
The Microsoft Server service contains a stack buffer overflow vulnerability in the handling of Remote Procedure Call (RPC) messages.
Exploit code for this vulnerability is publicly available, and the vulnerability is being currently exploited in the wild.
