The Server service running on Microsoft Windows XP leaks authentication information.
The Server service (
srvsvc.dll) is a component of the Server Message Block (SMB), and its follow-on, Common Internet File System (CIFS). These are network protocols that Windows uses to share files, printers, serial ports, and communicate between computers. If the Server service is running on Microsoft Windows XP, a remote attacker may be able to access it anonymously via a named pipe. In addition, if that attacker supplies the service with a specially crafted message, they will receive a response that may allow them to determine what other users are accessing a shared resource.
This vulnerability affects Microsoft Windows XP SP 1, Windows XP SP 2, and Windows XP 64-Bit Edition SP 1.
A remote, unauthenticated attacker may be able to access authentication information for users running Microsoft Windows XP.
Microsoft has released Microsoft Security Bulletin MS05-007 to address this issue.
