Title: Internet Anywhere Mail Server Multiple Buffer Overflow Vulnerabilities

Severity: MODERATE

Description:

True North Software's Internet Anywhere Mail Server has various weaknesses that could allow an attacker to remotely crash the server running this software.. The POP3 commands "list", "retr" .uidl" and "user" and the SMTP command "vrfy", if sent with abnormally long arguments, will crash the server. These limits seem to be around 200 characters for the POP3 commands, and around 250 characters for the SMTP command.

Currently, these problems have only been reliably remotely exploited as DoS attacks, however, it is conceivable that a remote shell exploit could be created.

Affected Products:

  • True North Software Internet Anywhere Mail Server 2.3.0
  • True North Software Internet Anywhere Mail Server 2.3.1
