multiple buffer overflow vulnerabilities.");

"EasyMail Objects, a set of COM objects for supporting email 
protocols, is installed on the remote Windows host.  It may have been 
bundled with a third-party application, such as Oracle Document 
Capture, Earthlink internet access software, Borland Caliber RM 
Client, and FrontRange Heat.

The SMTP component of the version of this control installed on the
remote host reportedly contains multiple buffer overflows involving 
the AddAttachment and SubmitToExpress methods that could lead to 
arbitrary code execution on the affected system.  Successful 
exploitation requires, though, that an attacker trick a user on the
affected host into visiting a specially crafted web page.");
