Next Generation Security Software notified Symantec that a specially crafted email could potentially create a Denial of Service (DoS) condition on an end user system. The malicious message would require a significantly longer than normal time to process, which could cause the client system to lose connection with the mail server. The email client will try to download the message again the next time it connects to the mail server, and again lose connection. This cycle would be repeated until the malicious message was deleted from the mail server.
