DESCRIPTION:
A vulnerability has been reported in some Symantec products, which
can be exploited by malicious, local users to cause a DoS (Denial of
Service).

The vulnerability is caused due to an error within the Internet Email
Auto-Protect feature when scanning outgoing email messages. This can
be exploited to cause a stack overflow via an email message
containing an overly long (greater than 951 characters) string in the
"To:", "From:", or "Subject" fields.

Successful exploitation crashes the Internet E-mail real-time
protection service and results in subsequent outgoing SMTP email
messages not being scanned.

The vulnerability is reported in the following products:
* Symantec AntiVirus Corporate Edition version 9.x and 10.0
* Symantec Client Security 2.0.x and 3.0.x
