A vulnerability in ICS/IMail Server 2006 allows remote attackers to execute arbitrary code on vulnerable installations of the Ipswitch Collaboration Suite and IMail. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SMTP daemon. A lack of bounds checking during the parsing of long strings contained within the characters ‘@’ and ‘:’ leads to a stack overflow vulnerability.
