Title: IPSwitch IMail SMTP Buffer Overflow Vulnerability
Severity: HIGH
Description:
IMail is a Windows NT/2000-based e-mail server from IPSwitch.
A vulnerability exists in at least one version of the IMail SMTP daemon.
The IMail SMTP daemon passes certain SMTP requests to a section of code which handles mailing lists. A flaw exists in this code which leads IMail to improperly validate user-supplied input in such requests.
As a result, a buffer overflow can be triggered by a remote attacker, by inserting in an SMTP request the name of a mailing list hosted by the vulnerable server.
If approximately 829 characters of properly-structured code are also included in such a request's "From:" field, it will be executed with SYSTEM-level privilege.
This can result in the remote execution of arbitrary hostile code on the system hosting IMail.
