"The remote host is running Computer Associates' Secure Content
Manager, a gateway product for filtering messaging and web traffic.

The HTTP Gateway component ('icihttp.exe') of the version of Secure
Content Manager installed on the remote host does not sufficiently
check responses to FTP 'LIST' and 'PASV' commands before copying them
into a stack buffer. An unauthenticated, remote attacker can leverage
these issues to crash the affected service or to execute arbitrary
code on the affected host with SYSTEM privileges.");
