Please read the contents of this bulletin and take actions appropriate for your organization. Thank you, Dave Lingren Iowa Communications Network 515-725-4795 Office 515-707-1638 Cell 515-234-2446 Pager Microsoft Security Bulletin: MS03-039 Buffer Overrun In RPCSS Service Could Allow Code Execution (824146) http://www.microsoft.com/technet/security/bulletin/MS03-039.asp Originally Posted: September 10, 2003 Impact of vulnerability: Run code of attacker's choice Maximum Severity Rating: Critical Affected Software: * Microsoft Windows NT Workstation 4.0 * Microsoft Windows NT Server(r) 4.0 * Microsoft Windows NT Server 4.0, Terminal Server Edition * Microsoft Windows 2000 * Microsoft Windows XP * Microsoft Windows Server 2003 Not Affected Software: * Microsoft Windows Millennium Edition Technical Details: There are three identified vulnerabilities in the part of RPCSS Service that deals with RPC messages for DCOM activation- two that could allow arbitrary code execution and one that could result in a denial of service. The flaws result from incorrect handling of malformed messages. These particular vulnerabilities affect the Distributed Component Object Model (DCOM) interface within the RPCSS Service. This interface handles DCOM object activation requests that are sent from one machine to another. An attacker who successfully exploited these vulnerabilities could be able to run code with Local System privileges on an affected system, or could cause the RPCSS Service to fail. The attacker could then be able to take any action on the system, including installing programs, viewing, changing or deleting data, or creating new accounts with full privileges. To exploit these vulnerabilities, an attacker could create a program to send a malformed RPC message to a vulnerable system targeting the RPCSS Service. Solution: Systems administrators should apply the patch as soon as possible. NOTE: The fix provided by this patch supersedes the one included in Microsoft Security Bulletin MS03-026. Microsoft is also planning to host a live discussion regarding this new vulnerability.
