Buffer Overrun in MDAC Function Could Allow Code Execution (832483) 1.0 is an advanced program which satisfies you with a collection of components that provides the underlying functionality for a number of database operations, such as connecting to remote databases and returning data to a client.

When a client system on a network tries to see a list of computers that are running SQL Server and that reside on the network, it sends a broadcast request to all the devices that are on the network. Because of a vulnerability in a specific MDAC component, an attacker could respond to this request with a specially-crafted packet that could cause a buffer overflow.

An attacker who successfully exploited this vulnerability could gain the same level of privileges over the system as the program that initiated the broadcast request. The actions an attacker could carry out would be dependent on the permissions under which the program using MDAC ran. If the program ran with limited privileges, an attacker would be limited accordingly; however, if the program ran under the local system context, the attacker would have the same level of permissions.

Since the original version of MDAC on your system may have changed from updates available on the Microsoft Web site, recommend using the following tool to determine the version of MDAC you have on your system: Microsoft Knowledge Base article 301202 "HOW TO: Check for MDAC Version" discusses this tool and explains how to use it. Also, Microsoft Knowledge Base article 231943 discusses the release history of the different versions of MDAC.

Mitigating factors:

1. For an attack to be successful an attacker would have to simulate a SQL server that is on the same IP subnet as the target system.
2. When a client system on a network tries to see a list of computers that are running SQL Server and that reside on the network, it sends a broadcast request to all the devices that are on the network. A target system must initiate such a broadcast request to be vulnerable to an attack. An attacker would have no way of launching this first step but would have to wait for anyone to enumerate computers that are running SQL Server on the same subnet. Also, a system is not vulnerable by having these SQL management tools installed.
3. Code executed on the client system would only run under the privileges of the client program that made the broadcast request.

Microsoft Internet Explorer 6.0 Incorrect VBScript Handling can Allow Web Pages to Read Local Files Q318089 is a highly-efficient, high-quality update which resolves the "Incorrect VBScript Handling in Internet Explorer can Allow Web Pages to Read Local Files" security vulnerability in Internet Explorer, and is discussed in Microsoft Security Bulletin MS02-009. Download now to prevent a malicious user from using an unauthorized Web site to read the contents of files on your local computer.

This vulnerability exists because VBScript that is created dynamically in Internet Explorer can result in the script being assigned invalid permissions, which gives the script the ability to read your local files, if the path to the file is known. This update prevents a malicious user from running VBScript in an unauthorized Web site to read the contents of files on your computer.

Microsoft Exchange Server 5.5 Authentication Flaw Could Allow Unauthorized Users To Authenticate To SMTP Service 05.05.55.2655 provides you an effective yet convenient to use SMTP service installs by default as part of Windows 2000 server products and as part of the Internet Mail Connector (IMC) for Microsoft Exchange Server 5.5. (The IMC, also known as the Microsoft Exchange Internet Mail Service, provides access and message exchange to and from any system that uses SMTP). A vulnerability results in both services because of a flaw in the way they handle a valid response from the NTLM authentication layer of the underlying operating system.

By design, the Windows 2000 SMTP service and the Exchange Server 5.5 IMC, upon receiving notification from the NTLM authentication layer that a user has been authenticated, should perform additional checks before granting the user access to the service. The vulnerability results because the affected services don't perform this additional checking correctly. In some cases, this could result in the SMTP service granting access to a user solely on the basis of their ability to successfully authenticate to the server.

An attacker who exploited the vulnerability could gain only user-level privileges on the SMTP service, thereby enabling the attacker to use the service but not to administer it. The most likely purpose in exploiting the vulnerability would be to perform mail relaying via the server.
