A vulnerability was reported in IBM Lotus Domino iCalendar. A remote user can execute arbitrary code on the target system.|
A remote user can send a calendar request with a specially crafted MAILTO header value to trigger a stack overflow and execute arbitrary code on the target system. The code will run with the privileges of the target 'nrouter.exe' service (System privileges).
The vendor was notified on August 26, 2008.
An anonymous researcher reported this vulnerability via Tipping Point's Zero Day Initiative and MWR InfoSecurity reported this vulnerability.
A remote user can execute arbitrary code on the target system.|
The vendor has issued a fix (8.0.2 FP5, 8.5.1 FP2, 8.5.2).|

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
systems with vulnerable installations of IBM Lotus Domino.
Authentication is not required to exploit this vulnerability.
The specific flaw exists within the nrouter.exe service while processing
a malformed e-mail. The process copies the contents of the MAILTO header
within a calendar request into a fixed size stack buffer. By providing
enough data this buffer can overflow leading to arbitrary code execution
under the context of the SYSTEM user.
-- Vendor Response:
IBM has issued an update to correct this vulnerability. More
