A vulnerability exists within IMail that allows remote attackers to gain SYSTEM level access to servers running IMail's SMTP daemon (versions 6.06 and below). The vulnerability stems from the IMail SMTP daemon not doing proper bounds checking on various input data that gets passed to the IMail Mailing List handler code. If an attacker crafts a special buffer and sends it to a remote IMail SMTP server it is possible that an attacker can remotely execute code (commands) on the IMail system.
