Microsoft Outlook mailto Command Line Switch Injection
------------------------------------------------------------------------


SUMMARY

<http://office.microsoft.com/outlook/> Microsoft Outlook provides "an
integrated solution for managing and organizing e-mail messages,
schedules, tasks, notes, contacts, and other information". Remote
exploitation of an input validation error in the handling of "mailto" URIs
by Microsoft Corp.'s Outlook may allow arbitrary code execution.

DETAILS

Vulnerable Systems:
* Microsoft Outlook 2007 on Windows XP SP2

It is possible to construct a "mailto" URI which causes the web browser to
pass extra command line switches to Outlook. These switches can modify
Outlook's account configuration.

Analysis:
Exploitation of this vulnerability may allow an attacker to access
sensitive information or take complete control of an affected system. In
order to exploit this vulnerability, an attacker would have to convince a
user to view an attacker-controlled website.

Workaround:
Disabling the "mailto" URI handler will prevent exploitation of this
vulnerability. However, doing so will also disable e-mail links within all
applications.

Vendor response:
Microsoft has addressed this vulnerability with Security Bulletin
MS08-015. For more information, consult their bulletin at the following
