Ipswitch IMail IMAP Daemon SUBSCRIBE Stack Overflow Vulnerability
------------------------------------------------------------------------


SUMMARY

A vulnerability allows attackers to execute arbitrary code on vulnerable
installations of Ipswitch IMail and ICS server. Authentication is required
to exploit this vulnerability.

DETAILS

listening by default on TCP port 143. By providing an overly long string
as the argument, an exploitable stack-based buffer overflow occurs.
