Lotus Domino IMAP buffer overflow vulnerability
 Technote (FAQ)
 
Question
VeriSign iDefense VCP contacted IBM® Lotus® to report a potential buffer overflow vulnerability with the Domino® IMAP server task.
The advisory can be accessed at the following link:
http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=605
 
Cause
If the IMAP server task is enabled on a Domino server, and an attacker is able to telnet to the server, it is possible for an attacker to execute arbitrary code resulting in a buffer overflow denial of service.
In order for an attacker to successfully exploit this vulnerability, they must accomplish the following:

-- Lotus Domino server must be configured for IMAP
-- Attacker needs to establish a TCP session with IMAP Domino server on TCP port 143
-- Authenticate with valid credentials
-- Execute arbitrary code

 
Answer
This issue was reported to Quality Engineering as SPR# PRAD74LKW5, and has been fixed in Domino releases 6.5.6 Fix Pack 2 (FP2), 7.0.2 Fix Pack 3 (FP3), 7.0.3 and 8.0. Refer to the Upgrade Central site for details on upgrading Notes/Domino.
Workaround
Employ firewalls to limit access to Domino servers over IMAP. This will mitigate exposure to this vulnerability.
