Ipswitch IMail IMAP Daemon SUBSCRIBE Stack Overflow Vulnerability

CVE ID	CVE-2007-2795
CVSS SCORE
AFFECTED VENDORS	Ipswitch
AFFECTED PRODUCTS	IMail
TREND MICRO CUSTOMER PROTECTION	Trend Micro TippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID ['2068']. For further product information on the TippingPoint IPS: http://www.tippingpoint.com
VULNERABILITY DETAILS	This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Ipswitch IMail and ICS server. Authentication is required to exploit this vulnerability. The specific flaw exists due to a lack of bounds checking during the parsing of arguments to the SUBSCRIBE IMAP command sent to the IMAP daemon listening by default on TCP port 143. By providing an overly long string as the argument, an exploitable stack-based buffer overflow occurs.
