Ipswitch IMail Server/Collaboration Suite IMAP FETCH Command Overflow
Medium Nessus Plugin ID 21051
The remote IMAP server is affected by a buffer overflow vulnerability.
The remote host is running Ipswitch Collaboration Suite / IMail Secure Server / IMail Server, commercial messaging and collaboration suites for Windows. According to its banner, the version of Ipswitch Collaboration Suite / IMail Secure Server / IMail Server installed on the remote host has a buffer overflow issue in its IMAP server component. Using a specially crafted FETCH command with excessive data, an authenticated attacker can crash the IMAP server on the affected host, thereby denying service to legitimate users, and possibly execute arbitrary code as LOCAL SYSTEM.
Upgrade to version 2006.03 of the appropriate application.
