Microsoft Security Bulletin MS03-048

Cumulative Security Update for Internet Explorer (824145)

Severity: Critical
Vulnerabilities:

• ExecCommand Cross Domain Vulnerability - CAN-2003-0814
  Three vulnerabilities that involve the cross-domain security model of Internet Explorer, which keeps windows of different domains from sharing information. These vulnerabilities could result in the execution of script in the My Computer zone. To exploit one of these vulnerabilities, an attacker would have to host a malicious Web site that contains a Web page that is designed to exploit the particular vulnerability and then persuade a user to view the Web page. The attacker could also create an HTML e-mail message that designed to exploit one of these vulnerabilities and persuade the user to view the HTML e-mail message. After the user has visited the malicious Web site or viewed the malicious HTML e-mail message an attacker who exploited one of these vulnerabilities could access information from other Web sites, access files on a user's system, and run arbitrary code on a user's system. This code would run in the security context of the currently logged on user
• Function Pointer Override Cross Domain Vulnerability - CAN-2003-0815
  Three vulnerabilities that involve the cross-domain security model of Internet Explorer, which keeps windows of different domains from sharing information. These vulnerabilities could result in the execution of script in the My Computer zone. To exploit one of these vulnerabilities, an attacker would have to host a malicious Web site that contains a Web page that is designed to exploit the particular vulnerability and then persuade a user to view the Web page. The attacker could also create an HTML e-mail message that designed to exploit one of these vulnerabilities and persuade the user to view the HTML e-mail message. After the user has visited the malicious Web site or viewed the malicious HTML e-mail message an attacker who exploited one of these vulnerabilities could access information from other Web sites, access files on a user's system, and run arbitrary code on a user's system. This code would run in the security context of the currently logged on user
• Script URLs Cross Domain Vulnerability - CAN-2003-0816
  Three vulnerabilities that involve the cross-domain security model of Internet Explorer, which keeps windows of different domains from sharing information. These vulnerabilities could result in the execution of script in the My Computer zone. To exploit one of these vulnerabilities, an attacker would have to host a malicious Web site that contains a Web page that is designed to exploit the particular vulnerability and then persuade a user to view the Web page. The attacker could also create an HTML e-mail message that designed to exploit one of these vulnerabilities and persuade the user to view the HTML e-mail message. After the user has visited the malicious Web site or viewed the malicious HTML e-mail message an attacker who exploited one of these vulnerabilities could access information from other Web sites, access files on a user's system, and run arbitrary code on a user's system. This code would run in the security context of the currently logged on user
• XML Object Vulnerability - CAN-2003-0817
  A vulnerability that involves the way that zone information is passed to an XML object within Internet Explorer. This vulnerability could allow an attacker to read local files on a user's system. To exploit this vulnerability, an attacker would have to host a malicious Web site that contains a Web page that is designed to exploit the particular vulnerability and then persuade a user to view the Web page. The attacker could also create an HTML e-mail message that is designed to exploit this vulnerability and persuade the user to view the HTML e-mail message. After the user visits the malicious Web site or views the malicious HTML e-mail message, the user would then be prompted to download an HTML file. If the user accepts the download of this HTML file, an attacker could read local files that are in a known location on the user's system.
• Drag-and-Drop Operation Vulnerability - CAN-2003-0823
  A vulnerability that involves performing a drag-and-drop operation during dynamic HTML (DHTML) events in Internet Explorer. This vulnerability could allow a file to be saved in a target location on the user's system if the user clicks a link. No dialog box would request that the user approve this download. To exploit one of these vulnerabilities, an attacker would have to host a malicious Web site that contains a Web page that has a specially-crafted link. The attacker would then have to persuade a user to click that link. The attacker could also create an HTML e-mail message that has a specially-crafted link, and then persuade the user to view the HTML e-mail message and then click the malicious link. If the user clicked this link, code of the attacker's choice could be saved on the user's computer in a targeted location.

Microsoft Security Bulletin MS03-049

Buffer Overrun in the Workstation Service Could Allow Code Execution (828749)

Severity: Critical
Vulnerabilities:

• Workstation Service Buffer Overrun - CAN-2003-0812
  A security vulnerability exists in the Workstation service that could allow remote code execution on an affected system. This vulnerability results because of an unchecked buffer in the Workstation service.

Microsoft Security Bulletin MS03-050

Vulnerability in Microsoft Word and Microsoft Excel Could Allow Arbitrary Code to Run (831527)

Severity: Important
Vulnerabilities:

• Microsoft Word Vulnerability - CAN-2003-0820
  A security vulnerability exists in Microsoft Word that could allow malicious code execution. This vulnerability exists due to to the way Word checks the length of a data value (Macro names) embedded in a document. If a specially crafted document were to be opened it could overflow a data value in Word and allow arbitrary code to be executed. If successfully exploited, an attacker could then take the same actions as the user had permissions to carry out, such as adding, changing or deleting data or files, communicating with a web site or formatting the hard drive.
• Microsoft Excel Vulnerability - CAN-2003-0821
  A security vulnerability exists in Microsoft Excel that could allow malicious code execution. This vulnerability exists because of the method Excel uses to check the spreadsheet before reading the macro instructions. If successfully exploited, an attacker could craft a malicious file that could bypass the macro security model. If an affected spreadsheet was opened, this vulnerability could allow a malicious macro embedded in the file to be executed automatically, regardless of the level at which the macro security is set. The malicious macro could then take the same actions that the user had permissions to carry out, such as adding, changing or deleting data or files, communicating with a web site or formatting the hard drive.

Microsoft Security Bulletin MS03-051

Buffer Overrun in Microsoft FrontPage Server Extensions Could Allow Code Execution (813360)

Severity: Critical
Vulnerabilities:

• Buffer Overrun vulnerability - CAN-2003-0822
  The first vulnerability exists because of a buffer overrun in the remote debug functionality of FrontPage Server Extensions. This functionality enables users to remotely connect to a server running FrontPage Server Extensions and remotely debug content using, for example, Visual Interdev. An attacker who successfully exploited this vulnerability could be able to run code with IWAM_machinename account privileges on an affected system, or could cause FrontPage Server Extensions to fail.
• SmartHTML interpreter vulnerability - CAN-2003-0824
  The second vulnerability is a Denial of Service vulnerability that exists in the SmartHTML interpreter. This functionality is made up of a variety of dynamic link library files, and exists to support certain types of dynamic web content. An attacker who successfully exploited this vulnerability could cause a server running Front Page Server Extensions to temporarily stop responding to requests.
