VULNERABILITY DETAILS

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell Netware Groupwise SMTP daemon. Authentication is not required to exploit this vulnerability.

The specific flaw exists during the parsing of malformed RCPT verb arguments to the SMTP daemon. When an overly long e-mail address is received an off-by-one condition is triggered which minimally will cause a denial of service and can result in arbitrary code execution.
