A remote code execution vulnerability exists in Microsoft Outlook. An attacker could exploit this vulnerability when Outlook parses a file and processes a malformed VEVENT record.

If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.

• An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
• MAPI is not a valid attack vector for this issue due to Exchange's handling of iCal calendar data embedded in messages or in .ICS attachments.

Microsoft has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.

• Modify the Access Control List on the “MapiCvt Class”registry key. Modifying the Access Control List on the MapiCvt Class registry key helps protect the affected system from attempts to exploit this vulnerability. To modify the MapiCvt Class registry key, follow these steps.

What is the scope of the vulnerability?
A remote code execution vulnerability exists in Microsoft Outlook. An attacker could exploit this vulnerability when Outlook parses a file and processes a malformed VEVENT record.

If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.

What causes the vulnerability?
Outlook does not perform sufficient data validation when processing the contents of an .iCal meeting request. When Outlook opens a specially crafted .iCal meeting request and parses a malformed VEVENT request, it may corrupt system memory in such a way that an attacker could execute arbitrary code.

What is an .iCal meeting request?
An iCal is used to create a meeting request to a recipient over the Internet, or outside the organization.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could take complete control of the affected system.

How could an attacker exploit the vulnerability?
An attacker could try to exploit the vulnerability by creating a specially crafted .ICS (iCal) file or embed the contents of an iCal calendar request in the body of a specially crafted e-mail and send it to a user of Outlook who connects to a POP, IMAP or HTTP server to retrieve their e-mail.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

Could the vulnerability be exploited over the Internet?
Yes. An attacker could try to exploit this vulnerability over the Internet. Firewall best practices and standard default firewall configurations can help protect against attacks that originate from the Internet. Microsoft has provided information about how you can help protect your PC. End users can visit the Protect Your PC Web site. IT professionals can visit the Security Guidance Center Web site.

What does the update do?
The update removes the vulnerability by modifying the way that Outlook validates the length of an .iCal meeting request before it passes the message to the allocated buffer.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through responsible disclosure.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

A denial of service vulnerability exists in Outlook in its processing of e-mail header information. An attacker who successfully exploited the vulnerability could send a malformed e-mail to a user of Outlook that would cause the Outlook client to fail under certain circumstances. The Outlook client would continue to fail so long as the malformed e-mail message remained on the e-mail server. The e-mail message could be deleted by an e-mail administrator, or by the user via another e-mail client such as Outlook Web Access or Outlook Express, after which point the Outlook client would again function normally.

• The vulnerability is a denial of service vulnerability only. The attacker would not be able to access the user's e-mail or system in any way. The vulnerability could not be used to read, delete, create, or alter the user's e-mail.
• If an attacker was able to send a malformed e-mail that successfully exploited this vulnerability, the malformed e-mail could be deleted either by an e-mail administrator, or by the user via another e-mail client such as Outlook Web Access or Outlook Express. Once the specially malformed e-mail has been removed, normal operation would resume.

We have not identified any workarounds for this vulnerability.

What is the scope of the vulnerability?
This is a denial of service vulnerability. An attacker who exploited this vulnerability could cause the affected system to stop responding. During that time, the server cannot respond to requests.

What causes the vulnerability?
The vulnerability results because of the way Outlook processes e-mail header information.

What might an attacker use the vulnerability to do?
Any anonymous user who could deliver a specially crafted message to the affected system could try to exploit this vulnerability.

Who could exploit the vulnerability?
On Outlook, any anonymous user who could deliver a specially crafted message to the affected system could try to exploit this vulnerability.

How could an attacker exploit the vulnerability?
An attacker could try to exploit the vulnerability by creating a specially crafted message and sending the message to an affected system. The message could then cause Outlook to fail.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do?
The update removes the vulnerability by modifying the way that Outlook validates the length of the header in the message.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2006-1305.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

A remote code execution vulnerability exists in Microsoft Outlook. An attacker could exploit this vulnerability when Outlook parses an .oss file.

If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.

• An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
• In a Web-based attack scenario, an attacker would have to host a Web site that contains an Office Saved Searches (.oss) file that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site.
• The vulnerability cannot be exploited automatically through e-mail. For an attack to be successful, a user must open an attachment that is sent in an e-mail message.

• Do not open or save Office Saved Searches (.oss) files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file.

What is the scope of the vulnerability?
A remote code execution vulnerability exists in Microsoft Outlook. An attacker could exploit this vulnerability when Outlook parses an Office Saved Searches (.oss) file.

If a user were logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.

What causes the vulnerability?
Outlook does not perform sufficient data validation when processing the contents of .oss file. When Outlook opens a specially crafted .oss and parses the request, it may corrupt system memory in such a way that an attacker could execute arbitrary code.

What is an Office Saved Searches (.oss) File?
Saved Searches are virtual folders that contain views of e-mail items that satisfy specific search criteria. The specific search criteria are stored in .oss file.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could take complete control of the affected system.

How could an attacker exploit the vulnerability?
An attacker could try to exploit the vulnerability by creating a specially crafted .oss file in a specially crafted e-mail and send it to a user of Outlook who connects to a POP, IMAP or HTTP server to retrieve their e-mail.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

Could the vulnerability be exploited over the Internet?
Yes. An attacker could try to exploit this vulnerability over the Internet. Firewall best practices and standard default firewall configurations can help protect against attacks that originate from the Internet. Microsoft has provided information about how you can help protect your PC. End users can visit the Protect Your PC Web site. IT professionals can visit the Security Guidance Center Web site.

What does the update do?
The update removes the ability to save these searches as well as removing the ability to open these searches.

Does this update contain any changes to functionality?
Yes. After the update for Outlook 2000, Outlook 2002, or Outlook 2003 is installed, users will not be able to save these searches as well as the ability to open these Searches. For more information, see Cannot open or save Office Saved Searches files in Outlook (KB925542).
