A remote overflow exists in MailEnable. MailEnable fails to check bounds for input passed to "A001 AUTHENTICATE <buffer>" resulting in a buffer overflow. With a specially crafted request greater than 1016 bytes, an attacker can overwrite the ECX and EAX registers causing arbitrary code execution, resulting in a loss of integrity.
