Ipswitch : Security Vulnerabilities, CVEs, Published In 2001 (Denial of service)

The webmail interface for Ipswitch IMail 7.04 and earlier allows remote authenticated users to cause a denial of service (crash) via a mailbox name that contains a large number of . (dot) or other characters to programs such as (1) readmail.cgi or (2) printmail.cgi, possibly due to a buffer overflow that may allow execution of arbitrary code.

IPSwitch IMail 6.0.5 allows remote attackers to cause a denial of service using the SMTP AUTH command by sending a base64-encoded user password whose length is between 80 and 136 bytes.
